ListPopupWindow使用

public class MainActivity extends ActionBarActivity {  
private EditText mEditText;  
private ListPopupWindow mListPop;  
private List lists = new ArrayList();  
    @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(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();  
            }  
        });  
    }  
  
}  

布局就一个Edittext
