1,首先编写layout文件mmp_dialog_layout.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/tv_dialog_title"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@color/MMPMainBlue"
        android:lineSpacingExtra="2dp"
        android:padding="8dp"
        android:text="@string/mmp_dialog_title"
        android:textColor="@color/white"
        android:textSize="@dimen/dimen_huge"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/tv_dialog_content"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:layout_marginEnd="16dp"
        android:lineSpacingExtra="2dp"
        android:text="内容"
        android:textSize="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/tv_dialog_title" />

    <TextView
        android:id="@+id/tv_sure"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:layout_marginEnd="16dp"
        android:layout_marginBottom="16dp"
        android:text="@string/mmp_positive"
        android:textColor="#4588F5"
        android:textSize="16dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/tv_dialog_content" />

    <TextView
        android:id="@+id/tv_cancle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="32dp"
        android:text="@string/mmp_negative"
        android:textColor="#4588F5"
        android:textSize="16dp"
        app:layout_constraintEnd_toStartOf="@+id/tv_sure"
        app:layout_constraintTop_toBottomOf="@+id/tv_dialog_content"
        app:layout_constraintTop_toTopOf="@+id/tv_sure" />
</android.support.constraint.ConstraintLayout>

文字资源 /values/string.xml

    <string name="mmp_dialog_title">温馨提示</string>
    <string name="mmp_positive">确定</string>
    <string name="mmp_negative">取消</string>行,途径%d个城市,游

2,自定义MMPDialog.java

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.support.v4.app.FragmentActivity;
import android.support.v7.app.AlertDialog;
import android.text.TextUtils;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import com.csair.mmpmobile.R;

public class MMPDialog {
    public interface Onclick {
        void onPositive();

        void onNegative();
    }

    static String str_dialog_title = "", str_dialog_content = "", str_sure = "", str_cancle = "";

    public static MMPDialogImp build(FragmentActivity activity) {
        return new MMPDialogImp().setActivity(activity);
    }

    public static class MMPDialogImp extends DialogFragment {
        FragmentActivity activity;
        private Onclick onclick;

        TextView tv_dialog_title, tv_dialog_content, tv_sure, tv_cancle;

        private MMPDialogImp setActivity(FragmentActivity activity) {
            this.activity = activity;
            return this;
        }

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
            LayoutInflater inflater = getActivity().getLayoutInflater();
            final View view = inflater.inflate(R.layout.mmp_dialog_layout, null);
            tv_dialog_title = view.findViewById(R.id.tv_dialog_title);
            tv_dialog_content = view.findViewById(R.id.tv_dialog_content);
            tv_sure = view.findViewById(R.id.tv_sure);
            tv_cancle = view.findViewById(R.id.tv_cancle);

            if (!TextUtils.isEmpty(str_dialog_title)) {
                tv_dialog_title.setText(str_dialog_title);
            }
            if (!TextUtils.isEmpty(str_dialog_content)) {
                tv_dialog_content.setText(str_dialog_content);
            }
            if (!TextUtils.isEmpty(str_sure)) {
                tv_sure.setText(str_sure);
            }
            if (!TextUtils.isEmpty(str_cancle)) {
                tv_cancle.setText(str_cancle);
            }

            if (onclick != null) {
                tv_sure.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        onclick.onPositive();
                        dismiss();
                    }
                });
                tv_cancle.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        onclick.onNegative();
                        dismiss();
                    }
                });
            }

            builder.setView(view);
            return builder.create();
        }


        @Override
        public void onAttach(Context context) {
            super.onAttach(context);
        }

        @Override
        public void onStart() {
            super.onStart();

            //在此设置大小宽高
            Dialog dialog = getDialog();
            if (dialog != null) {
                DisplayMetrics displayMetrics = new DisplayMetrics();
                getActivity().getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
                dialog.getWindow().setLayout((int) (displayMetrics.widthPixels * 0.9),
                        ViewGroup.LayoutParams.WRAP_CONTENT);
            }
        }

        @Override
        public void onDestroy() {
            super.onDestroy();
        }

        public MMPDialogImp setTitle(String str) {
            str_dialog_title = str;
            return this;
        }

        public MMPDialogImp setContent(String str) {
            str_dialog_content = str;
            return this;
        }

        public MMPDialogImp setNegative(String str) {
            str_sure = str;
            return this;
        }

        public MMPDialogImp setPositive(String str) {
            str_cancle = str;
            return this;
        }

        public MMPDialogImp setOnclick(Onclick onClick) {
            this.onclick = onClick;
            return this;
        }

        //静态调用方法
        public void show() {
            if (null == activity) throw new NullPointerException();
            show(activity.getSupportFragmentManager(), "MMPDialog");
        }
    }
}

3,调用如下:

MMPDialog.build(LoginActivity.this).setContent("系统检测到您不是在常用设备登陆,请录入手机号进行验证。")
                                .setOnclick(new MMPDialog.Onclick() {
                                    @Override
                                    public void onPositive() {
                                        mVH.showVerigyArea(getModifiedStartInfo(), mVH.mLoginCallback);
                                    }

                                    @Override
                                    public void onNegative() {

                                    }
                                }).show();
