android.content.res.Resources $ NotFoundException：string资源ID＃0x0

我正在开发一个Android应用程序，从MySQL数据库中读取数据，我面临这个错误。 我有这个XML布局：

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/wardNumber" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="3dp" android:text="Ward Number" android:textSize="22dp"/> <TextView android:id="@+id/dateTime" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/wardNumber" android:layout_alignParentRight="true" android:layout_marginRight="3dp" android:text="Date-Time" /> <TextView android:id="@+id/name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/dateTime" android:layout_alignBottom="@+id/dateTime" android:layout_alignLeft="@+id/wardNumber" android:layout_marginLeft="3dp" android:text="Name" /> </RelativeLayout> 

这是我的Java文件：

 public ApplicationAdapter(Context context, List<Application> items) { super(context, R.layout.app_custom_list, items); this.items = items; } @Override public int getCount() { return items.size(); } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if(v == null) { LayoutInflater li = LayoutInflater.from(getContext()); v = li.inflate(R.layout.app_custom_list, null); } Application app = items.get(position); if(app != null) { // ImageView icon = (ImageView)v.findViewById(R.id.appIcon); TextView wardNumber = (TextView)v.findViewById(R.id.wardNumber); TextView name = (TextView)v.findViewById(R.id.name); // LinearLayout ratingCntr = (LinearLayout)v.findViewById(R.id.ratingCntr); TextView dateTime = (TextView)v.findViewById(R.id.dateTime); // if(icon != null) { // Resources res = getContext().getResources(); // String sIcon = "com.sj.jsondemo:drawable/" + app.getIcon(); // icon.setImageDrawable(res.getDrawable(res.getIdentifier(sIcon, null, null))); // } if(wardNumber != null) wardNumber.setText(app.getTitle()); if(name != null) name.setText(app.getTitle()); if(dateTime != null) { dateTime.setText(app.getTotalDl()); // NumberFormat nf = NumberFormat.getNumberInstance(); // dateTime.setText(nf.format(app.getTotalDl())+" dl"); } } return v; } } 

当这个Activity被调用时，我收到这个错误信息：

我不知道如何解决这个错误。

Answer 1

更改

 dateTime.setText(app.getTotalDl()); 

至

 dateTime.setText(String.valueOf(app.getTotalDl())); 

有不同版本的setText – 一个接受一个string，一个接受一个int资源ID。 如果你传递一个整数，它会尝试寻找相应的string资源ID – 它找不到，这是你的错误。

我想app.getTotalDl()返回一个int。 你需要明确地告诉setText把它设置为这个int的String值。

setText（int resid） vs setText（CharSequence文本）

Answer 2

更换

 dateTime.setText(app.getTotalDl()); 

同

 dateTime.setText(""+app.getTotalDl()); 

Answer 3

当您尝试在Edittext或textview设置文本时，您应该只传递String格式。

 dateTime.setText(app.getTotalDl()); 

至

 dateTime.setText(String.valueOf(app.getTotalDl()));
