问一个人他是否想打电话对话。

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.Toast;

public class Firstclass extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {    
        super.onCreate(savedInstanceState);    
        setContentView(R.layout.first);

        ImageView imageViewCall = (ImageView) findViewById(R.id.ring_mig);

        imageViewCall.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v){
                try{
                    showDialog("0728570527");
                } catch (Exception e){
                    e.printStackTrace();
                }                   
            }    
        });    
    }

    public void showDialog(final String phone) throws Exception {
        AlertDialog.Builder builder = new AlertDialog.Builder(Firstclass.this);

        builder.setMessage("Ring: " + phone);       

        builder.setPositiveButton("Ring", new DialogInterface.OnClickListener(){
            @Override
            public void onClick(DialogInterface dialog, int which){

                Intent callIntent = new Intent(Intent.ACTION_DIAL);// (Intent.ACTION_CALL);                 
                callIntent.setData(Uri.parse("tel:" + phone));
                startActivity(callIntent);

                dialog.dismiss();
            }
        });

        builder.setNegativeButton("Abort", new DialogInterface.OnClickListener(){   
            @Override
            public void onClick(DialogInterface dialog, int which){
                dialog.dismiss();
            }
        });         
        builder.show();
    }    
}

试试这个:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Confirm");
builder.setMessage("Are you sure?");

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        // Do nothing but close the dialog

        dialog.dismiss();
    }
});

builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        // Do nothing
        dialog.dismiss();
    }
});

AlertDialog alert = builder.create();
alert.show();

1.创建AlertDialog，设置消息、标题和正面、负面按钮:

final AlertDialog alertDialog = new AlertDialog.Builder(this)
                        .setCancelable(false)
                        .setTitle("Confirmation")
                        .setMessage("Do you want to remove this Picture?")
                        .setPositiveButton("Yes",null)
                        .setNegativeButton("No",null)
                        .create();

2.现在在DialogInterface上找到两个按钮，然后单击setOnClickListener():

alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
            @Override
            public void onShow(DialogInterface dialogInterface) {
                Button yesButton = (alertDialog).getButton(android.app.AlertDialog.BUTTON_POSITIVE);
                Button noButton = (alertDialog).getButton(android.app.AlertDialog.BUTTON_NEGATIVE);
                yesButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        //Now Background Class To Update Operator State
                        alertDialog.dismiss();
                        Toast.makeText(GroundEditActivity.this, "Click on Yes", Toast.LENGTH_SHORT).show();
                        //Do Something here 
                    }
                });

                noButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        alertDialog.dismiss();
                        Toast.makeText(GroundEditActivity.this, "Click on No", Toast.LENGTH_SHORT).show();
                        //Do Some Thing Here 
                    }
                });
            }
        });

3.To 显示警报对话框：

alertDialog.show();

注意:不要忘记AlertDialog的Final Keyword。

你可以在Kotlin中轻松完成:

 alert("Testing alerts") {
    title = "Alert"
    yesButton { toast("Yess!!!") }
    noButton { }
}.show()

AlertDialog.Builder altBx = new AlertDialog.Builder(this);
    altBx.setTitle("My dialog box");
    altBx.setMessage("Welcome, Please Enter your name");
    altBx.setIcon(R.drawable.logo);

    altBx.setPositiveButton("Ok", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          if(edt.getText().toString().length()!=0)
          {
              // Show any message
          }
          else 
          {

          }
      }
    });
    altBx.setNeutralButton("Cancel", new DialogInterface.OnClickListener()
    {
      public void onClick(DialogInterface dialog, int which)
      {
          //show any message
      }

    });
  altBx.show();  

芬兰湾的科特林的实现。

你可以像这样创建一个简单的函数:

fun dialogYesOrNo(
        activity: Activity,
        title: String,
        message: String,
        listener: DialogInterface.OnClickListener
    ) {
        val builder = AlertDialog.Builder(activity)
        builder.setPositiveButton("Yes", DialogInterface.OnClickListener { dialog, id ->
            dialog.dismiss()
            listener.onClick(dialog, id)
        })
        builder.setNegativeButton("No", null)
        val alert = builder.create()
        alert.setTitle(title)
        alert.setMessage(message)
        alert.show()
    }

像这样叫它:

dialogYesOrNo(
  this,
  "Question",
  "Would you like to eat?",
  DialogInterface.OnClickListener { dialog, id ->
    // do whatever you need to do when user presses "Yes"
  }
})
