我正在尝试做一个android导航抽屉。
GoogleMap.java
public class GoogleMap extends FragmentActivity {
// Google Map
private com.google.android.gms.maps.GoogleMap map;
private String[] drawerListViewItems;
private DrawerLayout drawerLayout;
private ListView drawerListView;
private ActionBarDrawerToggle actionBarDrawerToggle;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
// get list items from strings.xml
drawerListViewItems = getResources().getStringArray(R.array.items);
// get ListView defined in activity_main.xml
drawerListView = (ListView) findViewById(R.id.left_drawer);
// Set the adapter for the list view
drawerListView.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_listview_item, drawerListViewItems));
// App Icon
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
);
// Set actionBarDrawerToggle as the DrawerListener
drawerLayout.setDrawerListener(actionBarDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
// just styling option add shadow the right edge of the drawer
drawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
drawerListView.setOnItemClickListener(new DrawerItemClickListener());
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// call ActionBarDrawerToggle.onOptionsItemSelected(), if it returns true
// then it has handled the app icon touch event
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
actionBarDrawerToggle.syncState();
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView parent, View view, int position, long id) {
Toast.makeText(GoogleMap.this, ((TextView)view).getText(), Toast.LENGTH_LONG).show();
drawerLayout.closeDrawer(drawerListView);
}
}
/**
* function to load map. If map is not created it will create it for you
* */
private void initilizeMap() {
if (map == null) {
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(
R.id.map)).getMap();
map.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(1.32814,103.80679) , 11.0f) );
// check if map is created successfully or not
if (map == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
@Override
protected void onResume() {
super.onResume();
initilizeMap();
}
}
main.xml中

我不确定哪个部分出了问题。我按照教程：Navigation Drawer
我测试了设置谷歌地图部分，它工作正常。只有在我尝试添加导航抽屉时才会出现错误。
任何指南？提前谢谢。
答案 0 :(得分：0)
您的drawer_listview_item应该只包含TextView。也就是说，删除LinearLayout。
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#fff"
android:textSize="20sp"
android:gravity="center_vertical"
android:paddingStart="14.5sp"
android:paddingEnd="14.5sp"
android:minHeight="35sp"
/>
logcat的：
Caused by: java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.TextView
另一个指标：
java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView
