BadTokenException:无法添加窗口-令牌null无效；您的活动正在进行吗?在活动中 [英] BadTokenException: Unable to add window -- token null is not valid; is your activity running? in activity.isFinishing statment
问题描述
如果用户仍处于当前活动状态，则在几秒钟后，我需要显示一个popUpWindow.我实施了stament，检查活动是否未完成/销毁，然后显示Popup，并且对于周末用户而言，它可以正常工作:)(在活动之间缓慢单击)，但在高压力测试中(活动正在重新创建，完成，快速移动)活动到活动)，这给了我这个错误:
I have a popUpWindow that need to by displayed, after couple of seconds if the user is still on current activity. I implemented stament that check if the activity isnt finished/destroyed and then display the Popup, and it works fine, for weekend users :) ( slowly clicking from activity to activity) but in high pressuretests ( activities are recreating, finished, fast move form activity to activity) that gives me that error :

推荐答案
尝试以下代码:
new Handler().postDelayed(new Runnable(){
public void run() {
popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER,0,0);
}
}, 200L);
代替:
popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER,0,0);
还要确保将ActivityName.this作为上下文传递..而不是getApplicationContext()
Also make sure you pass ActivityName.this as context.. not getApplicationContext()
尝试用以下代码替换showPopUpWindow()中的runnable代码:
Try replace your runnable code in showPopUpWindow() with this:
runOnUiThread(new Runnable() {
@Override
public void run() {
if (!isFinishing()) {
popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER, 0, 0);
}
}
});
