Question

我想点击一个按钮打开一个弹出视图，但PopUp背后的活动应该是可见的，因为创建的PopUp的背景需要是透明的。

Answer 1

你可以这样做

final Dialog nagDialog = new Dialog(MyActivity.this,android.R.style.Theme_Translucent_NoTitleBar);
                nagDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
                nagDialog.setCancelable(true);
                nagDialog.setContentView(R.layout.temp);


                nagDialog.show();

其中temp是您的transperent布局。

Answer 2

我的弹出代码： -

LayoutInflater layoutInflater  =     (LayoutInflater)IOStatusActivity.this.getSystemService(LAYOUT_INFLATER_SERVICE)    
final View popupView = layoutInflater.inflate(R.layout.popupai, null);  

final PopupWindow popupWindowDi = new PopupWindow(popupView,  LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);  

final   TextView txtReadVal = (TextView)popupView.findViewById(R.id.lblPopUpAiReadFrmPLC);
final   EditText txtExpVal = (EditText)popupView.findViewById(R.id.txtPopUpAiExpVal);
Button btnDismiss = (Button)popupView.findViewById(R.id.btnPopUpAiCancle);                          
btnDismiss.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
popupWindowDi.dismiss();
}});`
