Android ListPopupWindow的使用

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：

 

ListPopupWindow可以用在下拉式清單、查詢結果顯示、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);//設定ListPopupWindow的錨點，即關聯PopupWindow的顯示位置和這個錨點        mListPop.setModal(true);//設定是否是模式        mListPop.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView parent, View view,int position, long id) {mEditText.setText(lists.get(position));mListPop.dismiss();}});        mEditText.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {mListPop.show();}});    }}
