Android popupwindow使用心得（一）

標籤：

最近項目中好多地方用到popupwindow，感覺這個控制項還是非常重要的。所以把使用心得總結下，廢話不多說，直接上代碼。

public class MainActivity extends Activity {/** * 選擇按鈕 */private Button mSelectTypeBtn;/** * 顯示選擇的內容 */private TextView mSelectedType;private PopupWindow mPopupWindow;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);        mSelectTypeBtn = (Button) findViewById(R.id.btn_select_type);mSelectedType = (TextView) findViewById(R.id.tv_type);mSelectTypeBtn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {showSelectTypeWindow();}});}private void showSelectTypeWindow() {LinearLayout contentView = (LinearLayout) getLayoutInflater().inflate(R.layout.hd_type_view, null);ListView lv = (ListView) contentView.findViewById(R.id.hd_type_listview);final String[] types = getResources().getStringArray(R.array.hd_type_array);ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.hd_type_view_item, types);lv.setAdapter(adapter);        lv.setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {return MotionEvent.ACTION_MOVE == event.getAction() ? true: false;}});lv.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {mSelectedType.setText(types[position]);mPopupWindow.dismiss();}});mPopupWindow = new PopupWindow(contentView, LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT, true);mPopupWindow.setAnimationStyle(R.style.popwin_anim_style);mPopupWindow.setBackgroundDrawable(new ColorDrawable(-00000));mPopupWindow.showAtLocation(findViewById(R.id.parent_lay),Gravity.CENTER | Gravity.CENTER, 0, 0);}}

這裡的 popupwindow裡我沒有自訂，直接使用Android內建的。下一篇文章裡將會寫一個自訂的popupwindow的
