DrawerLayout一个简单的实例（与ActionBar无关）

官方的Demo里有DrawerLayout的例子，涉及到ActionBar，这里不用ActionBar，手痒，写个超级简单的小Demo，备着以后或许会用到。

看代码：

DrawerActivity.java

public class DrawerActivity extends Activity implements OnClickListener {
    private DrawerLayout mDrawerLayout = null;
    private Button bt1;
    private Button bt2;
    private Button bt3;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_drawer);
        bt1 = (Button) findViewById(R.id.btn);
        bt2 = (Button) findViewById(R.id.btn1);
        bt3 = (Button) findViewById(R.id.btn2);
        bt1.setOnClickListener(this);
        bt2.setOnClickListener(this);
        bt3.setOnClickListener(this);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerLayout.setDrawerListener(new DrawerListener() {

            @Override
            public void onDrawerStateChanged(int arg0) {
                Log.d("David", "onDrawerStateChanged arg0 = " + arg0);
            }

            @Override
            public void onDrawerSlide(View arg0, float arg1) {
                Log.d("David", "onDrawerSlide arg1 = " + arg1);
            }

            @Override
            public void onDrawerOpened(View arg0) {
                Log.d("David", "onDrawerOpened");
            }

            @Override
            public void onDrawerClosed(View arg0) {
                Log.d("David", "onDrawerClosed");
            }
        });
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn:
                mDrawerLayout.openDrawer(Gravity.LEFT);
                Toast.makeText(this, "bt1111111111", Toast.LENGTH_LONG).show();
                break;
            case R.id.btn1:
                Toast.makeText(this, "bt2222222222", Toast.LENGTH_LONG).show();
                break;
            case R.id.btn2:
                Toast.makeText(this, "bt33333333333", Toast.LENGTH_LONG).show();
                break;
            default:
                break;
        }
    }

}
