用ToggleButton和ImageView实现不同状态下显示的切换

时间：2024-04-07 08:07:18

靠，写的时候第一次因为把implements OnCheckedChangeListener这里实现的接口写错了，搞了很久，

后来发现又少了这两句错了

btn = (ToggleButton) findViewById(R.id.toggleButton1);
view = (ImageView) findViewById(R.id.imageView1);

后来又发现把这里private ImageView view;的Imageview写成ImageButton了

够了够了，细心细心

1：空间设置代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".MainActivity" >

    <ToggleButton

        android:id="@+id/toggleButton1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true"

        android:text="ToggleButton" />

    <ImageView

        android:id="@+id/imageView1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_below="@+id/toggleButton1"

        android:layout_marginTop="102dp"

        android:background="@drawable/off" />

</RelativeLayout>

２：主文件

package com.g.Deng;

import android.media.ToneGenerator;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.widget.CompoundButton;

import android.widget.CompoundButton.OnCheckedChangeListener;

import android.widget.ImageView;

import android.widget.ToggleButton;

public class MainActivity extends Activity implements OnCheckedChangeListener{

    //定义两个控件

    private ToggleButton btn;

    private ImageView view;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        //一定不要忘记这里，给两个空间附初值

        btn = (ToggleButton) findViewById(R.id.toggleButton1);

        view = (ImageView) findViewById(R.id.imageView1);

        /**

         * 设置监听器

         */

        btn.setOnCheckedChangeListener(this);

    }

    @Override

    public void onCheckedChanged(CompoundButton arg0, boolean arg1) {

        // TODO Auto-generated method stub

        //用arg1监听空间的状态，如果为真就打开，如果为假就关闭

        view.setBackgroundResource(arg1?R.drawable.on:R.drawable.off);

    }

}
