Android Material Design：ListPopupWindow

Android Material Design：ListPopupWindow

Android Material Design引入的ListPopupWindow，首先是一个PopupWindow，不过此PopupWindow内嵌一个List，给予此List设置一个Adapter，就相当Android为开发者做好了一个内置ListView的PopupWindows。

如图所示：

给出上述效果的代码实现：

package zhangphil.materialdesign;import android.app.Activity;import android.os.Bundle;import android.support.v7.widget.ListPopupWindow;import android.view.View;import android.widget.AdapterView;import android.widget.ArrayAdapter;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);final Button button = (Button) findViewById(R.id.button);button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {showListPopupWindow(button);}});}public void showListPopupWindow(View view) {String items[] = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };ListPopupWindow listPopupWindow = new ListPopupWindow(this);// ListView适配器listPopupWindow.setAdapter(new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, items));// 选择item的监听事件listPopupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int pos, long id) {Toast.makeText(getApplicationContext(), "选择:" + pos, Toast.LENGTH_SHORT).show();// listPopupWindow.dismiss();}});// 对话框的宽高listPopupWindow.setWidth(500);listPopupWindow.setHeight(600);// ListPopupWindow的锚,弹出框的位置是相对当前View的位置listPopupWindow.setAnchorView(view);// ListPopupWindow 距锚view的距离listPopupWindow.setHorizontalOffset(50);listPopupWindow.setVerticalOffset(100);listPopupWindow.setModal(false);listPopupWindow.show();}}

activity_main.xml只是一个仅仅含有一个Button的布局，Button用于触发、弹出ListPopupWindow，不在此赘述。
