**

1.自定义dialog类

**

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.widget.TextView;

import com.example.administrator.myapplication.R;

public class CustomeDialog extends Dialog{
    private String message;
    private TextView tvMessage;
    /**
     * 参数个数是自己的需求而定
     */
    public CustomeDialog( Context context,String message) {
        super(context, R.style.new_setting_dialog);
        this.message=message;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.view_dialog);
        tvMessage= (TextView) findViewById(R.id.tv_message);
        tvMessage.setText(message);
    }
}

**

2.dialog布局文件（布局文件居中则dialog显示居中）

**

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"

    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="300dp"
        android:layout_height="200dp"
        android:layout_centerInParent="true"
        android:layout_gravity="center"
        android:background="#fff0"
        android:orientation="vertical">
        <TextView
            android:layout_marginTop="20dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="提示" />
        <TextView
            android:id="@+id/tv_message"
            android:layout_marginTop="50dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="this is text message" />
    </LinearLayout>

</RelativeLayout>

**

3.使用

**

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.example.administrator.myapplication.R;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CustomeDialog customeDialog=new CustomeDialog(this,"aaaaaa");
        customeDialog.show();
    }
}
