現在、すべてのアクティビティにナビゲーション ドロワーを追加しようとしています。画面の端からスワイプするとナビゲーション ドロワーが表示されますが、そこには何もありません。黒い背景です。DrawerActivity のコードは次のとおりです。
public class DrawerActivity extends Activity {
public DrawerLayout drawerLayout;
public FrameLayout frameLayout;
public String[] mDrawerItems;
public ListView drawerList;
@Override
public void setContentView(int layoutResID) {
drawerLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.drawer_n_activity, null);
frameLayout = (FrameLayout) drawerLayout.findViewById(R.id.drawer_frame);
drawerList = (ListView) drawerLayout.findViewById(R.id.left_drawer);
getLayoutInflater().inflate(layoutResID, frameLayout, true);
super.setContentView(drawerLayout);
mDrawerItems = getResources().getStringArray(R.array.NAV_MENU_ITEMS);
drawerList.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, mDrawerItems));
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_drawer, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class StableArrayAdapter extends ArrayAdapter<String> {
HashMap<String, Integer> mIdMap = new HashMap<String, Integer>();
public StableArrayAdapter(Context context, int textViewResourceId,
List<String> objects) {
super(context, textViewResourceId, objects);
for (int i = 0; i < objects.size(); ++i) {
mIdMap.put(objects.get(i), i);
}
}
@Override
public long getItemId(int position) {
String item = getItem(position);
return mIdMap.get(item);
}
@Override
public boolean hasStableIds() {
return true;
}
}
}
