从文件path显示图像视图？

我需要通过使用文件名而不是从资源ID显示图像。

ImageView imgView=new ImageView(this); imgView.setBackgroundResource(R.drawable.img1); 

我在可绘制的文件夹中有图像img1。 我希望从文件中显示图像如何做到这一点。

Answer 1

Labeeb是正确的，为什么你需要使用path设置图像，如果你的资源已经铺在资源文件夹内，

这种path只有当你的图像存储在SD卡中时才需要。

并尝试下面的代码来设置存储在SD卡中的文件的位图图像。

 File imgFile = new File("/sdcard/Images/test_image.jpg"); if(imgFile.exists()){ Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath()); ImageView myImage = (ImageView) findViewById(R.id.imageviewTest); myImage.setImageBitmap(myBitmap); } 

并在清单文件中包含此权限：

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

Answer 2

我想你可以使用这个

 Bitmap bmImg = BitmapFactory.decodeFile("path of your img1"); imageView.setImageBitmap(bmImg); 

Answer 3

你也可以使用：

 File imgFile = new File(“filepath”); if(imgFile.exists()) { ImageView myImage = new ImageView(this); myImage.setImageURI(Uri.fromFile(imgFile)); } 

这将为您隐含的位图解码。

Answer 4

 String path = Environment.getExternalStorageDirectory()+ "/Images/test.jpg"; File imgFile = new File(path); if(imgFile.exists()) { Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath()); ImageView imageView=(ImageView)findViewById(R.id.imageView); imageView.setImageBitmap(myBitmap); } 

Answer 5

所有的答案都过时了。 出于这样的目的，最好使用毕加索 。 它有很多function，包括背景image processing。

我有没有提到它是超级简单易用的：

 Picasso.with(context).load(new File(...)).into(imageView); 

Answer 6

从官方网站： http : //developer.android.com/training/displaying-bitmaps/load-bitmap.html

 ImageView image = (ImageView) findViewById(R.id.imagePreview); try { image.setImageBitmap(decodeSampledBitmap(picFilename)); } catch (Exception e) { e.printStackTrace(); } 

这里的方法：

  private int calculateInSampleSize( BitmapFactory.Options options, int reqWidth, int reqHeight) { // Raw height and width of image final int height = options.outHeight; final int width = options.outWidth; int inSampleSize = 1; if (height > reqHeight || width > reqWidth) { final int halfHeight = height / 2; final int halfWidth = width / 2; // Calculate the largest inSampleSize value that is a power of 2 and keeps both // height and width larger than the requested height and width. while ((halfHeight / inSampleSize) > reqHeight && (halfWidth / inSampleSize) > reqWidth) { inSampleSize *= 2; } } return inSampleSize; } private Bitmap decodeSampledBitmap(String pathName, int reqWidth, int reqHeight) { // First decode with inJustDecodeBounds=true to check dimensions final BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeFile(pathName, options); // Calculate inSampleSize options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight); // Decode bitmap with inSampleSize set options.inJustDecodeBounds = false; return BitmapFactory.decodeFile(pathName, options); } //I added this to have a good approximation of the screen size: private Bitmap decodeSampledBitmap(String pathName) { Display display = getWindowManager().getDefaultDisplay(); Point size = new Point(); display.getSize(size); int width = size.x; int height = size.y; return decodeSampledBitmap(pathName, width, height); } 

Answer 7

您可以使用：

 ImageView imgView = new ImageView(this); InputStream is = getClass().getResourceAsStream("/drawable/" + fileName); imgView.setImageDrawable(Drawable.createFromStream(is, "")); 

Answer 8

您可以使用它来访问特定的文件夹，并获得特定的图像

  public void Retrieve(String path, String Name) { File imageFile = new File(path+Name); if(imageFile.exists()){ Bitmap myBitmap = BitmapFactory.decodeFile(path+Name); myImage = (ImageView) findViewById(R.id.savedImage); myImage.setImageBitmap(myBitmap); Toast.makeText(SaveImage.this, myBitmap.toString(), Toast.LENGTH_LONG).show(); } } 

然后你可以打电话

 Retrieve(Environment.getExternalStorageDirectory().toString()+"/Aqeel/Images/","Image2.PNG"); Toast.makeText(SaveImage.this, "Saved", Toast.LENGTH_LONG).show(); 

Answer 9

  public static Bitmap decodeFile(String path) { Bitmap b = null; File f = new File(path); // Decode image size BitmapFactory.Options o = new BitmapFactory.Options(); o.inJustDecodeBounds = true; FileInputStream fis = null; try { fis = new FileInputStream(f); BitmapFactory.decodeStream(fis, null, o); fis.close(); int IMAGE_MAX_SIZE = 1024; // maximum dimension limit int scale = 1; if (o.outHeight > IMAGE_MAX_SIZE || o.outWidth > IMAGE_MAX_SIZE) { scale = (int) Math.pow(2, (int) Math.round(Math.log(IMAGE_MAX_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5))); } // Decode with inSampleSize BitmapFactory.Options o2 = new BitmapFactory.Options(); o2.inSampleSize = scale; fis = new FileInputStream(f); b = BitmapFactory.decodeStream(fis, null, o2); fis.close(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return b; } public static Bitmap showBitmapFromFile(String file_path) { try { File imgFile = new File(file_path); if(imgFile.exists()){ Bitmap pic_Bitmap = decodeFile(file_path); return pic_Bitmap; } } catch (Exception e) { MyLog.e("Exception showBitmapFromFile"); return null; } return null; } 

如果您在列表视图中使用图像加载，然后使用Aquery概念。

https://github.com/AshishPsaini/AqueryExample

  AQuery aq= new AQuery((Activity) activity, convertView); //load image from file, down sample to target width of 250 pixels .gi File file=new File("//pic/path/here/aaaa.jpg"); if(aq!=null) aq.id(holder.pic_imageview).image(file, 250); 

Answer 10

onLoadImage满载

  private void onLoadImage(final String imagePath) { ImageSize targetSize = new ImageSize(imageView.getWidth(), imageView.getHeight()); // result Bitmap will be fit to this size //ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleto com.nostra13.universalimageloader.core.ImageLoader imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance(); imageLoader.init(ImageLoaderConfiguration.createDefault(getContext())); imageLoader.loadImage(imagePath, targetSize, new SimpleImageLoadingListener() { @Override public void onLoadingStarted(final String imageUri, View view) { super.onLoadingStarted(imageUri, view); progress2.setVisibility(View.VISIBLE); new Handler().post(new Runnable() { public void run() { progress2.setColorSchemeResources(android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light); // Picasso.with(getContext()).load(imagePath).into(imageView); // Picasso.with(getContext()).load(imagePath) .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE).into(imageView); Glide.with(getContext()) .load(imagePath) .asBitmap() .into(imageView); } }); } @Override public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) { if(view == null){ progress2.setVisibility(View.INVISIBLE); } 

// else {

  Log.e("onLoadImage","onLoadingComplete"); // progress2.setVisibility(View.INVISIBLE); // } // setLoagingCompileImage(); } @Override public void onLoadingFailed(String imageUri, View view, FailReason failReason) { super.onLoadingFailed(imageUri, view, failReason); if(view == null){ progress2.setVisibility(View.INVISIBLE); } Log.e("onLoadingFailed",imageUri); Log.e("onLoadingFailed",failReason.toString()); } @Override public void onLoadingCancelled(String imageUri, View view) { super.onLoadingCancelled(imageUri, view); if(view == null){ progress2.setVisibility(View.INVISIBLE); } Log.e("onLoadImage","onLoadingCancelled"); } }); }

如何在Android中显示来自文件夹path的图像

非常先：确保你有权限添加到Mainfest文件中：

  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

##：制作一个MyGallery类

公共类MyGallery扩展活动{

 private GridView gridView; private String _location; private String newFolder = "/IslamicGif/"; private String extStorageDirectory = Environment.getExternalStorageDirectory().toString(); private AdView mAdView; private ArrayList<Bitmap> photo = new ArrayList<Bitmap>(); public static String[] imageFileList; TextView gallerytxt; public static ImageAdapter imageAdapter; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.mygallery); /*if (MenuClass.mInterstitialAd.isLoaded()) { MenuClass.mInterstitialAd.show(); }*/ gallerytxt = (TextView) findViewById(R.id.gallerytxt); /*gallerytxt.setTextSize(20); int[] color = {Color.YELLOW,Color.WHITE}; float[] position = {0, 1}; Shader.TileMode tile_mode0= Shader.TileMode.REPEAT; // or TileMode.REPEAT; LinearGradient lin_grad0 = new LinearGradient(0, 0, 0, 200,color,position, tile_mode0); Shader shader_gradient0 = lin_grad0; gallerytxt.getPaint().setShader(shader_gradient0);*/ ImageButton btn_back = (ImageButton) findViewById(R.id.btn_back); btn_back.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { MyGallery.this.finish(); } }); mAdView = (AdView) findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder() .build(); mAdView.loadAd(adRequest); gridView = (GridView) findViewById(R.id.gridView); new MyGalleryAsy().execute(); gridView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) { // TODO Auto-generated method stub Intent intent = new Intent(MyGallery.this, ImageDetail.class); intent.putExtra("ImgUrl", imageFileList[pos]); //Toast.makeText(MyGallery.this,"image detail"+pos,Toast.LENGTH_LONG).show(); startActivity(intent); } }); } protected void onStart() { super.onStart(); if (ImageDetail.deleted) { photo = new ArrayList<Bitmap>(); new MyGalleryAsy().execute(); ImageDetail.deleted = false; } } public class MyGalleryAsy extends AsyncTask<Void, Void, Void> { private ProgressDialog dialog; Bitmap mBitmap; @Override protected void onPreExecute() { dialog = ProgressDialog.show(MyGallery.this, "", "Loading ...", true); dialog.show(); } @Override protected Void doInBackground(Void... arg0) { readImage(); return null; } @Override protected void onPostExecute(Void result) { dialog.dismiss(); DisplayMetrics displayMatrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(displayMatrics); int screenWidth = displayMatrics.widthPixels / 3; if (photo.size() > 0) { imageAdapter = new ImageAdapter(MyGallery.this, screenWidth); gridView.setAdapter(imageAdapter); } } } private void readImage() { // TODO Auto-generated method stub try { if (isSdPresent()) { _location = extStorageDirectory + newFolder; } else _location = getFilesDir() + newFolder; File file1 = new File(_location); if (file1.isDirectory()) { // sdCard == true imageFileList = file1.list(); if (imageFileList != null) { for (int i = 0; i < imageFileList.length; i++) { try { photo.add(BitmapFactory.decodeFile(_location + imageFileList[i].trim())); } catch (Exception e) { // TODO: handle exception //Toast.makeText(getApplicationContext(), e.toString(),Toast.LENGTH_LONG).show(); } } } } } catch (Exception e) { // TODO: handle exception } } public static boolean isSdPresent() { return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED); } public class ImageAdapter extends BaseAdapter { private Context context; private LayoutInflater layoutInflater; private int width; private int mGalleryItemBackground; public ImageAdapter(Context c) { context = c; } public ImageAdapter(Context c, int width) { context = c; this.width = width; } public int getCount() { return photo.size(); } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = layoutInflater.inflate(R.layout.galleryadapter, null); RelativeLayout layout = (RelativeLayout) v.findViewById(R.id.galleryLayout); ImageView imageView = new ImageView(context); layout.addView(imageView, new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, width)); imageView.setScaleType(ImageView.ScaleType.FIT_XY); layout.setLayoutParams(new GridView.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, width)); imageView.setImageBitmap(photo.get(position)); return v; } public void updateItemList(ArrayList<Bitmap> newItemList) { photo = newItemList; notifyDataSetChanged(); } } 

}

现在创build它的Xml类

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/bg" android:orientation="vertical"> <RelativeLayout android:id="@+id/relativeLayout" android:layout_width="match_parent" android:layout_height="56dp" android:background="@color/colorPrimary" android:minHeight="?attr/actionBarSize"> <TextView android:id="@+id/gallerytxt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:layout_gravity="center" android:fontFamily="@string/font_fontFamily_medium" android:text="My Gallery" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="@android:color/black" android:textStyle="bold" /> <ImageButton android:id="@+id/btn_back" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_centerVertical="true" android:layout_marginLeft="12dp" android:background="@drawable/ic_arrow_back_black_24dp" /> </RelativeLayout> <com.google.android.gms.ads.AdView android:id="@+id/adView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_gravity="center|bottom" android:visibility="gone" ads:adSize="BANNER" ads:adUnitId="@string/banner_id" /> <GridView android:id="@+id/gridView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/adView" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_below="@+id/relativeLayout" android:horizontalSpacing="5dp" android:numColumns="2" android:smoothScrollbar="true" android:verticalSpacing="5dp"></GridView> 

也使适配器galleryadapter.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" xmlns:ads="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:id="@+id/galleryLayout" android:padding="2dp">
