ActionBar导航(滑动抽屉)
官方的DrawerLayout有严重缺陷,这里只上代码。
public class MainActivity extends ActionBarActivity { private DrawerLayout mDrawerLayout; private ActionBarDrawerToggle mDrawerToggle; private ListView mDrawerList; private CharSequence mTitle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, 0, 0) { /** Called when a drawer has settled in a completely closed state. */ public void onDrawerClosed(View view) { supportInvalidateOptionsMenu(); } /** Called when a drawer has settled in a completely open state. */ public void onDrawerOpened(View drawerView) { supportInvalidateOptionsMenu(); } }; mDrawerLayout.setDrawerListener(mDrawerToggle); getSupportActionBar().setDisplayHomeAsUpEnabled(true); initListView(); } @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); mDrawerToggle.syncState(); onSectionAttached(0); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); mDrawerToggle.onConfigurationChanged(newConfig); } @Override public boolean onCreateOptionsMenu(Menu menu) { if (!mDrawerLayout.isDrawerOpen(mDrawerList)) { getMenuInflater().inflate(R.menu.main, menu); restoreActionBar(); return true; } return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } private void initListView() { mDrawerList = (ListView) findViewById(R.id.left_drawer); mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, getData())); mDrawerList.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // 响应事件 onSectionAttached(position); restoreActionBar(); } }); } private List<String> getData() { List<String> data = new ArrayList<String>(); data.add("菜单1"); data.add("菜单2"); return data; } private void restoreActionBar() { ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD); actionBar.setDisplayShowTitleEnabled(true); actionBar.setTitle(mTitle); } private void onSectionAttached(int position) { FragmentManager fragmentManager = getSupportFragmentManager(); if (position == 0) { fragmentManager.beginTransaction() .replace(R.id.content_frame, new MyFragmentA()).commit(); mTitle = getString(R.string.a); } else { fragmentManager.beginTransaction() .replace(R.id.content_frame, new MyFragmentB()).commit(); mTitle = getString(R.string.b); } } }activity_main.xml
