我的 PopupView 中有一个 LinearLayout,这个 LinearLayout 中有一个按钮。此按钮的事件侦听器工作正常,但按下(突出显示)的动画未启动。我做错了什么?求求你了!
public class PopupView extends View
{
private PopupWindow popUp;
private Button buttonOk;
private OnClickListener onClick;
private LayoutParams params;
private int popUpWidth = 0;
private int popUpHeight = 0;
private int popUpX, popUpY;
public PopupView(Context context, View parent)
{
super(context);
popUp = new PopupWindow(context);
popUpLayout = new LinearLayout(context);
buttonOk = new Button(context);
buttonOk.setText("OK");
buttonOk.setId(1);
params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
popUpLayout.setOrientation(LinearLayout.VERTICAL);
popUp.setContentView(popUpLayout);
onClick = new OnClickListener()
{
public void onClick (View v)
{
switch (v.getId())
{
case 1:
System.out.println("OK pressed!");
break;
case 2:
break;
}
}
};
buttonOk.setOnClickListener(onClick);
popUpLayout.removeAllViews();
popUpLayout.addView(buttonOk, params);
popUpWidth = 200;
popUpHeight = 400;
popUpX = 300;
popUpY = 300;
popUp.showAtLocation(parent, Gravity.NO_GRAVITY, popUpX, popUpY);
popUp.update(popUpX, popUpY, popUpWidth, popUpHeight);
}
}
