先弄个界面布局

大概是这个样子

这样比较省事

名字都是一样的

选择你的游戏

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="match_parent"
    tools:context="com.example.hp.myapplication1.MainActivity"
    android:orientation="vertical">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:text="Please choose a game"
        android:textSize="30dp"
        android:id="@+id/keyi" />

    <ImageView
        android:layout_width="200dp"
        android:layout_height="140dp"
        android:layout_gravity="center"
        android:id="@+id/tupian"
        tools:layout_editor_absoluteY="0dp"
        tools:layout_editor_absoluteX="0dp" />

    <RadioGroup
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:orientation="vertical"
        android:id="@+id/game"
        >

        <RadioGroup
            android:layout_marginTop="40dp"
            android:id="@+id/pl"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:orientation="horizontal"
            >

            <RadioButton

                android:id="@+id/game1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:checked="true"
                android:text="game1"
                android:textSize="20sp"
                />

            <RadioButton

                android:id="@+id/game2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="game2"
                android:textSize="20sp"/>
            <RadioButton

                android:id="@+id/game3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="game3"
                android:textSize="20sp"/>
        </RadioGroup>

        <RadioGroup

            android:id="@+id/pl2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:orientation="horizontal"
            >

            <RadioButton

                android:id="@+id/game4"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="game4"
                android:textSize="20sp"
                />

            <RadioButton

                android:id="@+id/game5"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="game5"
                android:textSize="20sp"/>

            <RadioButton

                android:id="@+id/game6"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="game6"
                android:textSize="20sp"/>
        </RadioGroup>
    </RadioGroup>

</LinearLayout>


然后关联JAVA
将定义该完成定义
将图片弄进去
把图片名字弄好
一一对应
完成了

package com.example.hp.myapplication1;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

        public class MainActivity extends AppCompatActivity {
        private TextView txkeyi;
        private RadioButton rbgame1;
        private RadioButton rbgame2;
        private RadioButton rbgame3;
        private RadioButton rbgame4;
        private RadioButton rbgame5;
        private RadioButton rbgame6;
        private RadioGroup plpl;
        private RadioGroup plpl2;
        private RadioGroup game;
        private ImageView ivtupian;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            txkeyi = (TextView) findViewById(R.id.keyi);
            rbgame1 = (RadioButton) findViewById(R.id.game1);
            rbgame2 = (RadioButton) findViewById(R.id.game2);
            rbgame3 = (RadioButton) findViewById(R.id.game3);
            rbgame4 = (RadioButton) findViewById(R.id.game4);
            rbgame5 = (RadioButton) findViewById(R.id.game5);
            rbgame6 = (RadioButton) findViewById(R.id.game6);
            plpl = (RadioGroup) findViewById(R.id.pl);
            plpl2 = (RadioGroup) findViewById(R.id.pl2);
            game = (RadioGroup) findViewById(R.id.game);
            ivtupian = (ImageView) findViewById(R.id.tupian);

            plpl.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {   //监听rgrg RadioGroup组
                @Override
                public void onCheckedChanged(RadioGroup radioGroup, int i) {
                    if (rbgame1.isChecked()) {
                        ivtupian.setImageResource(R.drawable.game1);
                        plpl2.clearCheck();
                    }
                    if (rbgame2.isChecked()) {
                        ivtupian.setImageResource(R.drawable.game2);
                        plpl2.clearCheck();
                    }
                    if (rbgame3.isChecked()) {
                        ivtupian.setImageResource(R.drawable.game3);
                        plpl2.clearCheck();
                    }

                }
            });
            plpl2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(RadioGroup radioGroup, int i) {
                    if (rbgame4.isChecked()) {
                        ivtupian.setImageResource(R.drawable.game4);
                        plpl.clearCheck();
                    }
                    if (rbgame5.isChecked()) {
                        ivtupian.setImageResource(R.drawable.game5);
                        plpl.clearCheck();
                    }
                    if (rbgame6.isChecked()) {
                        ivtupian.setImageResource(R.drawable.game6);
                        plpl.clearCheck();
                    }

                }
            });

        }
    }

 

然后就是第二个作业

<ImageView
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="center_horizontal"
android:id="@+id/picture" />

<Button
android:layout_marginTop="300dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="退出"
android:id="@+id/button" />

布局，不要太简单呀嘿嘿嘿

 

然后关联JAVA

public class MainActivity extends AppCompatActivity {
private Button btbutton;
private ImageView ivtupian;

然后真的没时间做了

容我再想想好嘛

老师我先交作业吧

先这样吧。。。
