AlertDialog setOnDismissListener不起作用

Question

我的活动打开一个对话框.当它关闭时,我需要ReloadTable()执行该功能.所以我试图使用,setOnDismissListener但它没有被触发.有人可以帮助我做错了吗？

谢谢!

AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.transaction, null);
builder = new AlertDialog.Builder(new ContextThemeWrapper(TransactionsList.this , R.style.dialogwithoutdim));
builder.setView(layout);
alertDialog = builder.create();
alertDialog.setOnDismissListener(new OnDismissListener() {
    public void onDismiss(final DialogInterface dialog) {
        ReloadTable();
    }
});

builder.show();

Answer 1

public class MyActivity extends Activity implements DialogInterface.OnCancelListener{
    @Override
    public void onCreate(Bundle state) {
       .....
       alertDialog.setOnCancelListener(this);
       alertDialog.show();
    }
    @Override
    public void onCancel(DialogInterface dialog) {
        dialog.dismiss();
        .....
    }
}

您必须将setOnCancelListener设置为AlertDialog.Builder:

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                this);
alertDialogBuilder.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                dialogmenu = false;
            }
        })

Answer 3

在这种情况下，您应该使用alertDialog.setOnCancelListener(listener),andalertDialog.setOnDismissListener与 一起使用dismissDialog(id)。
