Question

我想解除AlertDialog窗口，但是在点击“确定”或“取消”按钮时却没有，但是在调用某个操作时。实际上，我想用onResume函数创建对话框：

@Override
public void onResume() {
    super.onResume();
    alert = new AlertDialog.Builder(this);
    alert.setTitle("Stay stuck to a tag");
    alert.create().show();
}

然后在调用函数时退出它，如

private void dismissMyDiag() {
    alert.dismiss();
}

当然，我已经看到了通过onclick事件做到这一点的方式，这不是我想做的事情。有可能做这样的事吗？如果没有，对话框之王允许我这样做？

谢谢！

Answer 1

像这样获取alertDialog

AlertDialog dialog;
 alert = new AlertDialog.Builder(this);

dialog=alert.create().show();

然后致电

private void dismissMyDiag() {
    dialog.dismiss();
}

尝试这种方式：

final AlertDialog d = new AlertDialog.Builder(context)
                .setView(v)
                .setTitle(R.string.my_title)
                .setPositiveButton(android.R.string.ok,
                        new Dialog.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface d, int which) {
                                //Do nothing here. We override the onclick
                            }
                        })
                .setNegativeButton(android.R.string.cancel, null)
                .create();

        d.setOnShowListener(new DialogInterface.OnShowListener() {

            @Override
            public void onShow(DialogInterface dialog) {

                Button b = d.getButton(AlertDialog.BUTTON_POSITIVE);
                b.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View view) {
                        // TODO Do something

                        //Dismiss once everything is OK.
                        d.dismiss();
                    }
                });
            }
        });

我知道这是一个古老的问题，但希望它能对某些人有所帮助。您还可以为警报对话框创建自定义类并访问其漏洞项目可以显示和隐藏任何地方

package (Your_Pakage_Name);
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatDialogFragment;


public class AlertDailogbox extends AppCompatDialogFragment {

    String Title = null;
    String Msg = null;
    String TAG = "Alert Dialog Box";

    public AlertDailogbox(String title, String msg) {
        Title = title;
        Msg = msg;
        
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle(Title)
                .setMessage(Msg)
                .setIcon(R.drawable.ic_alert) //set icon if you want
                .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        
                    }
                });

        return builder.create();
    }
}

致电您的项目（活动）设置alertDialog类的全局变量

private AlertDailogbox alertDailogbox;

显示对话框的功能

private void showMsgDailog(String Title,String Msg){
    alertDailogbox = new AlertDailogbox(Title,Msg);
    alertDailogbox.setCancelable(false);
    alertDailogbox.show(getSupportFragmentManager(),"alert Dailog");
}

解雇结束

if(alertDailogbox != null)
       alertDailogbox.dismiss();

alerDailogeBox不为null检查其他必要的应用程序是否可能崩溃

在不单击按钮的情况下关闭AlertDialog
