我正在試圖製作一個簡單的導航抽屜,與材料指南相匹配。我沿着the official training。一切運行良好,只有漢堡包圖標上的水龍頭不會打開抽屜。我可以從側面輕掃打開抽屜,只有漢堡包不工作。我已經查了一些其他問題like this one,但沒有任何幫助。我錯過了什麼?Android 5漢堡包不打開抽屜
這裏是我的代碼:
Activity.java:
public class stream extends ActionBarActivity {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private String[] mDrawerTitles;
private ListView mDrawerList;
private Toolbar mToolbar;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_stream);
// Init the Support-toolbar
mToolbar = (Toolbar) findViewById(R.id.toolbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onBackPressed() {
if(mDrawerLayout.isDrawerOpen(Gravity.START|Gravity.LEFT)){
mDrawerLayout.closeDrawers();
return;
}
super.onBackPressed();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggle
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
