你可以创建Activity并扩展AppCompatActivity。然后在清单中加入下一种风格

<activity android:name=".YourCustomDialog"
            android:theme="Theme.AppCompat.Light.Dialog">
</activity>

充气它的按钮和TextViews

然后把这个当做一个对话。

例如，在linearLayout中，我填充下一个参数:

android:layout_width="300dp"
android:layout_height="wrap_content"

   new AlertDialog.Builder(v.getContext()).setMessage("msg to display!").show();

new AlertDialog.Builder(context)
    .setTitle("title")
    .setMessage("message")
    .setPositiveButton(android.R.string.ok, null)
    .show();

试试这段代码

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(MainActivity.this);

    // set title
    alertDialogBuilder.setTitle("AlertDialog Title");

    // set dialog message
    alertDialogBuilder
            .setMessage("Some Alert Dialog message.")
            .setCancelable(false)
            .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                            Toast.makeText(this, "OK button click ", Toast.LENGTH_SHORT).show();

                }
            })
            .setNegativeButton("CANCEL",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                           Toast.makeText(this, "CANCEL button click ", Toast.LENGTH_SHORT).show();

                    dialog.cancel();
                }
            });

    // create alert dialog
    AlertDialog alertDialog = alertDialogBuilder.create();

    // show it
    alertDialog.show();

这是在kotlin中完成的

val builder: AlertDialog.Builder = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            AlertDialog.Builder(this, android.R.style.Theme_Material_Dialog_Alert)
        } else {
            AlertDialog.Builder(this)
        }
        builder.setTitle("Delete Alert!")
                .setMessage("Are you want to delete this entry?")
                .setPositiveButton("YES") { dialog, which ->

                }
                .setNegativeButton("NO") { dialog, which ->

                }
                .setIcon(R.drawable.ic_launcher_foreground)
                .show()

我已经创建了一个对话框，用于询问Person是否想呼叫Person。

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

        builder.show();
    }
}
