Android ListPopupWindow的使用

其實像ListPopupWindow、PopupMenu的用法大致和PopupWindow的一樣！就不講了，相信用過PopupWindow的看一下就能明白。

先上個效果圖：

ListPopupWindow可以用在下拉列表、查詢結果顯示、歷史記錄、提示輸入等，當然PopupMenu也可以的。

直接貼代碼吧：

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);//設置ListPopupWindow的錨點，即關聯PopupWindow的顯示位置和這個錨點
        mListPop.setModal(true);//設置是否是模式
        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();
			}
		});
    }

}
