Android音乐、视频类APP常用控件：DraggablePanel（2）

附录文章1主要演示了如何使用DraggablePanel 的DraggableView。DraggablePanel除了DraggableView外，本身DraggablePanel与DraggableView不同的是，DraggableView是一个轻量级的“View”， 而DraggablePanel是一个重的面板、“平台”可以承载更重的如Android Fragment的组件。

写一个测试的MainActivity.java：

package zhangphil.demo;import com.github.pedrovgs.DraggableListener;import com.github.pedrovgs.DraggablePanel;import android.os.Bundle;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentActivity;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends FragmentActivity {	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		final DraggablePanel draggablePanel = (DraggablePanel) findViewById(R.id.draggable_panel);		findViewById(R.id.image).setOnClickListener(new OnClickListener() {			@Override			public void onClick(View v) {				draggablePanel.maximize();			}		});		// 注意！添加的监听事件需要放在初始化之前，否则可能无法正常达到监听效果。		draggablePanel.setDraggableListener(new DraggableListener() {			@Override			public void onMaximized() {				Toast.makeText(getApplication(), "onMaximized", Toast.LENGTH_SHORT).show();			}			@Override			public void onMinimized() {				Toast.makeText(getApplication(), "onMinimized", Toast.LENGTH_SHORT).show();			}			@Override			public void onClosedToLeft() {				Toast.makeText(getApplication(), "onClosedToLeft", Toast.LENGTH_SHORT).show();			}			@Override			public void onClosedToRight() {				Toast.makeText(getApplication(), "onClosedToRight", Toast.LENGTH_SHORT).show();			}		});		draggablePanel.setFragmentManager(getSupportFragmentManager());		draggablePanel.setTopFragment(new MyTopFragment());		draggablePanel.setBottomFragment(new MyBottomFragment());		draggablePanel.initializeView();	}	private static class MyTopFragment extends Fragment {		@Override		public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {			View v = inflater.inflate(android.R.layout.simple_list_item_1, null);			v.setBackgroundColor(0xFFEF5350);			TextView text = (TextView) v.findViewById(android.R.id.text1);			text.setText("zhang phil @ csdn , 顶");			return v;		}	}	private static class MyBottomFragment extends Fragment {		@Override		public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {			View v = inflater.inflate(android.R.layout.simple_list_item_1, null);			v.setBackgroundColor(0xFF42A5F5);			TextView text = (TextView) v.findViewById(android.R.id.text1);			text.setText("zhang phil @ csdn , 底");			return v;		}	}}

所需的activity_main.xml布局文件：

代码运行结果，从顶向底拖曳，然后到底后再水平向左拖曳，最终点击Android小机器人使之复位，如图所示：

代码中写了两个不同的Android Fragment加载到DraggablePanel中，分别为top和bottom。
