ActionBar导航(滑动抽屉)

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);
		}
	}
}
