Android控制項——ToggleButton多狀態按鈕(實現燈泡的開關)

標籤：tool   ashx   ctr   ipv4   eee   exit   nop   vsan   npe   

 

思路:通過點擊根據按鈕的選擇狀態與false狀態設定圖片的路徑

 1.布局檔案:

<LinearLayout 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:orientation="vertical"    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" >    <!-- textOn為true狀態，textOff為false狀態 -->    <ToggleButton        android:id="@+id/toggleButton1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="ToggleButton"        android:textOff="關"        android:textOn="開" />    <ImageView        android:id="@+id/imageView1"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="@drawable/img1" /></LinearLayout>

 

2.MainActivity.java

package com.example.mooc;import android.app.Activity;import android.os.Bundle;import android.widget.AutoCompleteTextView;import android.widget.Button;import android.widget.CompoundButton;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.ImageButton;import android.widget.ImageView;import android.widget.MultiAutoCompleteTextView;import android.widget.ToggleButton;public class MainActivity extends Activity implements OnCheckedChangeListener {    private Button login_button;    private ToggleButton toggleButton;    private ImageView imgView;    private ImageButton img_button;    private AutoCompleteTextView autoCompleteTextView1;    private MultiAutoCompleteTextView mutiple;    private String res[] = { "beijing1", "beijing2", "beijing3" };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        // 將布局檔案引入到Activity        setContentView(R.layout.toggle_button);        toggleButton = (ToggleButton) findViewById(R.id.toggleButton1);        imgView = (ImageView) findViewById(R.id.imageView1);        toggleButton.setOnCheckedChangeListener(this);    }    /**     * arg0:代表組件本身     * arg1代表選中狀態     */    @Override    public void onCheckedChanged(CompoundButton arg0, boolean arg1) {//        按鈕被點擊的時候此函數執行        imgView.setBackgroundResource(arg1?R.drawable.ic_launcher:R.drawable.img1);            }}

 

 

3.效果:（false的時候顯示收納袋，true的時候顯示安卓表徵圖）
