你好，我有一个抽屉导航，当通过滑动打开时 ---> 运行上帝，但是当我触摸操作栏时，这个应用程序损坏了
我的 XML:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff" >
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<LinearLayout
android:id="@+id/left_drawer_s"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/drawers"
android:layout_width="240dp"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:background="@color/REDAR_COLOR"
android:gravity="center_vertical"
android:orientation="horizontal" >
<ImageView
android:layout_width="80dp"
android:layout_height="80dp"
android:paddingLeft="20dp"
android:src="@drawable/ic_launcher" />
<LinearLayout
android:id="@+id/drawer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:background="@color/REDAR_COLOR"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Shohel Rana"
android:textSize="14sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:gravity="center"
android:text="test@gmail.com"
android:textSize="14sp" />
</LinearLayout>
</LinearLayout>
<ListView android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#fff"/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
还有我的 java 类:
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] nav_options;
private int restaurant_user_id = 0;
int position= 0;
public static drawer_menu drawer_menu_activity;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_menu);
drawer_menu_activity = this;
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
nav_options = getResources().getStringArray(R.array.nav_options);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
// Set the adapter for the list view
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, nav_options);
mDrawerList.setAdapter(adapter);
// Set the list's click listener
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
position = 1;
selectItem(position,restaurant_user_id);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.hello_world, /* "open drawer" description */
R.string.hello_world /* "close drawer" description */
) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu();
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
invalidateOptionsMenu();
}
};
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
/* The click listner for ListView in the navigation drawer */
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position,restaurant_user_id);
}
}
private void selectItem(int position, int restaurant_user_id) {
mDrawerLayout.closeDrawers();
Bundle args = new Bundle();
args.putInt("restaurant_user_id", restaurant_user_id);
args.putString("WEB_URL", WEB_URL);
switch (position){
case 0:
Log.v("POSITION" , "ES 0");
position=0;
Fragment main= new main();
main.setArguments(args);
FragmentManager fragmentManager_main = getFragmentManager();
fragmentManager_main.beginTransaction().replace(R.id.content_frame, main).commit();
break;
case 1:
Log.v("POSITION" , "ES 1");
position=1;
Fragment detail = new comments();
detail.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, detail).commit();
break;
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(mDrawerList);
mDrawerLayout.invalidate();
return true;
default: return super.onOptionsItemSelected(item);
}
}
控制台日志是

控制台市场抽屉_菜单.java:204是:
`mDrawerLayout.openDrawer(mDrawerList);`
请帮忙，问候!
最佳答案
尝试更改您的 onOptionsItemSelected 方法:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Pass the event to ActionBarDrawerToggle, if it returns
// true, then it has handled the app icon touch event
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle your other action bar items...
return super.onOptionsItemSelected(item);
}
这应该有效。
