ProgressDialog.dismiss() 显示时出现 IllegalArgumentException

Question

这是简单的代码：

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

谁能解释一下为什么 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();
 }

Answer 2

这是因为你的activity被摧毁了。在调用进度对话框之前，请检查您是否在 class 中调用了 finish()。谢谢
