Question

以下是简单的代码：

if (myProgressDialog.isShowing()) {
    myProgressDialog.dismiss();
}

有人可以解释为什么myProgressDialog.dismiss（）有时会导致以下异常：

java.lang.IllegalArgumentException: View=com.android.internal.policy.PhoneWindow$DecorView{83559f5 V.E...... R......D 0,0-1026,348} not attached to window manager

Answer 1

试试这个固定代码：

 if (YourActivity.this.isDestroyed()) { // or call isFinishing() if min sdk version < 17
    return;
 } 
 if (myProgressDialog != null && myProgressDialog.isShowing()) {
    myProgressDialog.dismiss();
 }

这是因为您的活动被破坏了。在调用进度对话框之前，检查是否在类中调用了finish（）。感谢
