Android导航抽屉切换图标向右
我的要求是下面的图片我的导航抽屉应该从右侧打开。 我已经实现了这一点。 我的导航抽屉从右向左打开。 但问题是切换图标总是在左侧。 我怎样才能设置切换图标的权利。 我检查了以下的问题，但没有一个人得到任何帮助。
更改切换button图像图标在导航抽屉从右到左
抽屉在右侧抽屉中切换
在这里input链接描述
这是我所尝试过的。
代码为我的布局activity_main.xml

提前致谢。
我为EndDrawerToggle类编写了一个非常类似于您的设置 – 一个DrawerLayout和一个结束alignment的抽屉View ，在一个具有自定义Toolbar的AppCompatActivity作为支持ActionBar 。
import android.app.Activity; import android.support.v4.view.GravityCompat; import android.support.v4.widget.DrawerLayout; import android.support.v7.graphics.drawable.DrawerArrowDrawable; import android.support.v7.widget.AppCompatImageButton; import android.support.v7.widget.Toolbar; import android.support.v7.widget.Toolbar.LayoutParams; import android.view.View; import android.view.View.OnClickListener; public class EndDrawerToggle implements DrawerLayout.DrawerListener { private DrawerLayout drawerLayout; private DrawerArrowDrawable arrowDrawable; private AppCompatImageButton toggleButton; private String openDrawerContentDesc; private String closeDrawerContentDesc; public EndDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes) { this.drawerLayout = drawerLayout; this.openDrawerContentDesc = activity.getString(openDrawerContentDescRes); this.closeDrawerContentDesc = activity.getString(closeDrawerContentDescRes); arrowDrawable = new DrawerArrowDrawable(toolbar.getContext()); arrowDrawable.setDirection(DrawerArrowDrawable.ARROW_DIRECTION_END); toggleButton = new AppCompatImageButton(toolbar.getContext(), null, R.attr.toolbarNavigationButtonStyle); toolbar.addView(toggleButton, new LayoutParams(GravityCompat.END)); toggleButton.setImageDrawable(arrowDrawable); toggleButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { toggle(); } } ); } public void syncState() { if (drawerLayout.isDrawerOpen(GravityCompat.END)) { setPosition(1f); } else { setPosition(0f); } } public void toggle() { if (drawerLayout.isDrawerOpen(GravityCompat.END)) { drawerLayout.closeDrawer(GravityCompat.END); } else { drawerLayout.openDrawer(GravityCompat.END); } } public void setPosition(float position) { if (position == 1f) { arrowDrawable.setVerticalMirror(true); toggleButton.setContentDescription(closeDrawerContentDesc); } else if (position == 0f) { arrowDrawable.setVerticalMirror(false); toggleButton.setContentDescription(openDrawerContentDesc); } arrowDrawable.setProgress(position); } @Override public void onDrawerSlide(View drawerView, float slideOffset) { setPosition(Math.min(1f, Math.max(0, slideOffset))); } @Override public void onDrawerOpened(View drawerView) { setPosition(1f); } @Override public void onDrawerClosed(View drawerView) { setPosition(0f); } @Override public void onDrawerStateChanged(int newState) { } }
在这种情况下， EndDrawerToggle类是ActionBarDrawerToggle的完全替代品，因此您不需要任何您现在拥有的设置。 所有DrawerListener方法仍然可用于重写，但是对于基本function来说， EndDrawerToggle ，因为EndDrawerToggle处理自己切换抽屉状态。 同样不需要自己处理切换点击，所以你也不需要导航OnClickListener 。
只需实例化切换，将其添加为DrawerListener ，并将其同步。 我build议同步onPostCreate()方法中的切换，以确保它在同步方向更改后正确同步。
private EndDrawerToggle drawerToggle; ... public void initNavigationDrawer() { NavigationView navigationView = ... ... drawerLayout = (DrawerLayout)findViewById(R.id.drawer); drawerToggle = new EndDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close); drawerLayout.addDrawerListener(drawerToggle); } @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); drawerToggle.syncState(); }
在你的Android清单中添加这一行：
android:supportsRtl="true"
到你的应用程序，像这样：
<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true"
然后在你的onCreate方法中，添加这一行：
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
警告:::这只适用于SdkVersion 17+，所以如果你的应用程序的目标是一个较低的最低SDK，你将不得不创build一个自定义菜单并重写OnCreateOptions方法（除非有另一种我不知道的方式，这是绝对可能）。
