由于使用 AlertDialog，我在运行时遇到窗口泄漏错误。
我已经指出了下面代码中的错误行:

@JavascriptInterface
public void moveToNextScreen() {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set title
alertDialogBuilder.setTitle("Your Title");
// set dialog message
alertDialogBuilder
.setMessage("Click yes!")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent i = new Intent(FirstActivity.this,SecondActivity.class);
startActivity(i);
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show(); --->leak window error
}
}
}
我不知道如何解决这个问题。
最佳答案
您收到错误是因为 ProgressDialog 正在运行，而您的 Activity 被销毁。您应该在开始新的 Activity 之前关闭对话框。
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
if (alertDialog != null && alertDialog.isShowing()) {
alertDialog.dismiss();
}
Intent i = new Intent(FirstActivity.this, SecondActivity.class);
startActivity(i);
}
});
希望对你有帮助!
关于android - Activity 在 alertDialog show() 方法处泄漏了窗口，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32065854/
