android-在popupwindow裏面過濾listview

我不能在popupwindow裏面過濾列表視圖。android-在popupwindow裏面過濾listview

它失敗，異常

android.view.WindowManager$BadTokenException: Unable to add window -- token [email protected] is not valid; is your activity running?

     at android.widget.TextView.setText(TextView.java:4312) 
     at android.widget.AbsListView.setFilterText(AbsListView.java:1944)

我顯示PopupWindow爲：

popupWindow.showAtLocation(getWindow().getDecorView(), Gravity.CENTER, 0, 0);

彈出佈局是

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 
    <EditText 
     android:hint="" /> 
    <ListView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
    </ListView> 
</RelativeLayout>

你能提供指針？

提供適用於listview的適配器代碼？ –

我解決了這個問題，通過使用對話框而不是popupwindow – GJain

我認爲問題在於您顯示的彈出窗口太早顯示。在runnable中使用showatlocation，如下所示

new Handler().postDelayed(new Runnable(){ 
    public void run() { 
     pwindow.showAtLocation(popupView, Gravity.CENTER, 0, 0); 
    } 
}, 100L);

問題是彈出窗口內的列表過濾。我能夠顯示彈出。但是，當列表過濾發生時，它會嘗試顯示另一個彈出窗口，引發異常。 – GJain

嘗試使用runnable，如果它工作或發佈您的代碼，將找出問題。 –
