Android ListPopupWindow的使用

其实像ListPopupWindow、PopupMenu的用法大致和PopupWindow的一样！就不讲了，相信用过PopupWindow的看一下就能明白。

先上个效果图：

ListPopupWindow可以用在下拉列表、查询结果显示、历史记录、提示输入等，当然PopupMenu也可以的。

直接贴代码吧：

public class MainActivity extends ActionBarActivity {
private EditText mEditText;
private ListPopupWindow mListPop;
private List<String> lists = new ArrayList<String>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        lists.add("one");
        lists.add("two");
        lists.add("three");
        mEditText = (EditText) findViewById(R.id.editText1);
        mListPop = new ListPopupWindow(this);
        mListPop.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, lists));
        mListPop.setWidth(LayoutParams.WRAP_CONTENT);
        mListPop.setHeight(LayoutParams.WRAP_CONTENT);
        mListPop.setAnchorView(mEditText);//设置ListPopupWindow的锚点，即关联PopupWindow的显示位置和这个锚点
        mListPop.setModal(true);//设置是否是模式
        mListPop.setOnItemClickListener(new OnItemClickListener() {
			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				mEditText.setText(lists.get(position));
				mListPop.dismiss();
			}
		});
        mEditText.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				mListPop.show();
			}
		});
    }

}

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.listpopupwindow.MainActivity" >
    <EditText
        android:id="@+id/editText1"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:ems="10" >
    </EditText>

</RelativeLayout>
