java - 创建类似“通知栏”的菜单

Question

我需要在我的应用程序底部创建一个类似通知栏的菜单。这意味着，您可以向右拖动通知栏？这也是我需要的。

例如，在拖动之前，菜单应保持在底部，如下所示

拖完之后应该是这样的

到目前为止，我处理过的所有菜单都与菜单按钮有关，但这个没有。我怎样才能创造出这样的东西？

use Sliding Drawer to achieve this

http://developer.android.com/reference/android/widget/SlidingDrawer.html

SlidingDrawerActivity.java

public class SlidingDrawerActivity extends Activity implements OnClickListener {
 Button slideButton, b1, b2, b3;
 SlidingDrawer slidingDrawer;

 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_sliding_drawer);
  slideButton = (Button) findViewById(R.id.slideButton);
  slidingDrawer = (SlidingDrawer) findViewById(R.id.SlidingDrawer);
  b1 = (Button) findViewById(R.id.Button01);
  b2 = (Button) findViewById(R.id.Button02);
  b3 = (Button) findViewById(R.id.Button03);
  b1.setOnClickListener(this);
  b2.setOnClickListener(this);
  b3.setOnClickListener(this);
  slidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
   @Override
   public void onDrawerOpened() {
    slideButton.setText("V");
   }
  });
  slidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {
   @Override
   public void onDrawerClosed() {
    slideButton.setText("^");
   }
  });
 }

 @Override
 public void onClick(View v) {
  Button b = (Button) v;
  Toast.makeText(SlidingDrawerActivity.this,
    b.getText() + " is Clicked :)", Toast.LENGTH_SHORT).show();
 }
}
