設置自己的佈局在彈出的窗口中的Android

我有一個彈出窗口的問題。我想用我自己的佈局創建彈出窗口。這是代碼：設置自己的佈局在彈出的窗口中的Android

public class PopupWindowView extends PopupWindow{ 

    PopupWindow popup; 
    boolean click = true; 
    LayoutParams params; 
    RelativeLayout mainLayout; 
    TextView tv; 
    LinearLayout layout; 
    ImageView chooseFlag; 

    public void createPopupWindow(Activity act){ 
     popup = new PopupWindow(act); 
     chooseFlag = (ImageView) act.findViewById(R.id.login_choose_flag); 
     mainLayout = (RelativeLayout) act.findViewById(R.id.login_layout); 
     tv = new TextView(act); 
     layout = new LinearLayout(act); 
     //layout = (LinearLayout) findViewById(R.id.popuplayout); 
     chooseFlag.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       if (click) { 
        int[] values = new int[2]; 
        v.getLocationOnScreen(values); 
        popup.showAtLocation(mainLayout, Gravity.NO_GRAVITY, 10, 10); 
        popup.update(values[0], values[1], 300, 80); 
        click = false; 
       } else { 
        popup.dismiss(); 
        click = true; 
       } 
      } 
     }); 
     params = new LayoutParams(LayoutParams.WRAP_CONTENT, 
       LayoutParams.WRAP_CONTENT); 
     layout.setOrientation(LinearLayout.VERTICAL); 
     tv.setText("Hi this is a sample text for popup window"); 
     layout.addView(tv, params); 
     popup.setContentView(layout); 
    } 
}

，這是佈局，我想在我的彈出窗口設置：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    > 

    <LinearLayout 
     android:id="@+id/popuplayout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@color/patient_button_bg"> 
    </LinearLayout> 

</LinearLayout>

在我的課，我不能使用findbyid方法，因爲這不是活動。我如何在我的課堂中設置我自己的彈出窗口中的佈局？

試試這個代碼：

private void showSortPopup(final Activity context, Point p) 
{ 
     // Inflate the popup_layout.xml 
     LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.llSortChangePopup); 
     LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View layout = layoutInflater.inflate(R.layout.sort_popup_layout, viewGroup); 

     // Creating the PopupWindow 
     changeSortPopUp = new PopupWindow(context); 
     changeSortPopUp.setContentView(layout); 
     changeSortPopUp.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT); 
     changeSortPopUp.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT); 
     changeSortPopUp.setFocusable(true); 

     // Some offset to align the popup a bit to the left, and a bit down, relative to button's position. 
     int OFFSET_X = -20; 
     int OFFSET_Y = 95; 

     // Clear the default translucent background 
     changeSortPopUp.setBackgroundDrawable(new BitmapDrawable()); 

     // Displaying the popup at the specified location, + offsets. 
     changeSortPopUp.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y); 


     // Getting a reference to Close button, and close the popup when clicked. 
     Button close = (Button) layout.findViewById(R.id.close); 
     close.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      changeSortPopUp.dismiss(); 
     } 
     }); 

}

有用，謝謝！ '清除默認的半透明背景'，它將我拉上了牆（尤其是沒有發現我的佈局造成了什麼） – YvesLeBorg 2017-04-18 15:51:11

嗨檢查這個post包括解決方案，以你的問題

試試這個代碼：

public class ShowPopUp extends Activity { 

PopupWindow popUp; 
LinearLayout layout; 
TextView tv; 
LayoutParams params; 
LinearLayout mainLayout; 
Button but; 
boolean click = true; 


public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    popUp = new PopupWindow(this); 
    layout = new LinearLayout(this); 
    mainLayout = new LinearLayout(this); 
    tv = new TextView(this); 
    but = new Button(this); 
    but.setText("Click Me"); 
    but.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 
      if (click) { 
       popUp.showAtLocation(mainLayout, Gravity.BOTTOM, 10, 10); 
       popUp.update(50, 50, 300, 80); 
       click = false; 
      } else { 
       popUp.dismiss(); 
       click = true; 
      } 
     } 

    }); 
    params = new LayoutParams(LayoutParams.WRAP_CONTENT, 
      LayoutParams.WRAP_CONTENT); 
    layout.setOrientation(LinearLayout.VERTICAL); 
    tv.setText("Hi this is a sample text for popup window"); 
    layout.addView(tv, params); 
    popUp.setContentView(layout); 
    // popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10); 
    mainLayout.addView(but, params); 
    setContentView(mainLayout); 
    } 
}

我不要;不想做，在活動。我想做自己的控制，它擴展了PopUpWindow – user1302569 2013-03-01 10:10:23

您可以使用LayoutInflater

LayoutInflater inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
View view = inflater.inflate(R.layout.custom_layout, null); //custom_layout is your xml file which contains popuplayout 
LinearLayout layout = (LinearLayout) view.findViewById(R.id.popuplayout);

我用你的解決方案，但我得到錯誤：java.lang.IllegalStateException：指定的子項已經有一個父項。您必須先調用子對象的父對象的removeView（）。 – user1302569 2013-03-01 08:50:47

根據例外情況，您似乎嘗試將以前添加到不同佈局的視圖添加到視圖中，請問您在哪一行獲取此異常？ – Waqas 2013-03-01 09:41:03

難道你不能調試，看看在哪個特定的行它thorws這個錯誤？從堆棧跟蹤中，您在preparePopup方法 – Waqas 2013-03-01 10:13:18

您可以使用下面的代碼。你需要爲此使用PopupWindow。

PopupWindow mpopup;

然後你需要膨脹你的看法。

View popUpView = getLayoutInflater().inflate(R.layout.activity_login, 
      null); // inflating popup layout 
    mpopup = new PopupWindow(popUpView, LayoutParams.FILL_PARENT, 
      LayoutParams.WRAP_CONTENT, true); // Creation of popup 
    mpopup.setAnimationStyle(android.R.style.Animation_Dialog); 
    mpopup.showAtLocation(popUpView, Gravity.CENTER, 0, 0); // Displaying popup

如果您的佈局有一些項目，那麼您需要將該項目與您的視圖綁定。

TextView some = (TextView) popUpView.findViewById(R.id.some);  
    Button btnCancel = (Button) popUpView.findViewById(R.id.btnCancel);

onClickListener您的彈出窗口項目。

btnCancel.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      mpopup.dismiss(); 
     } 
    });

可以使用mpopup.dismiss();

試試這個解散你PopupWindow ......

public void popUpWindow() { 
    final Dialog dialog = new Dialog(MainActivity.this); 
    dialog.setContentView(R.layout.client_details); 
    dialog.setTitle("Client Details"); 
    dialog.show(); 
}

alert=(Button)findViewById(R.id.click); 
    detail=(ImageView)findViewById(R.id.goDetail); 

    alert.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View arg0) { 
      // custom dialog 

      final Dialog dialog = new Dialog(context);

      dialog.setTitle(Html.fromHtml("<font color='#EC407A'>About</font>")); 
      Button dialogButton = (Button) dialog.findViewById(R.id.dialogOK);
