ToggleButton,就是開關按鈕,包括選中和未選中狀態,並且需要為不同的狀態設定不同的事件處理;
例如:使用圖片來展示ToggleButton不同的狀態;
MainActivity.java
package com.xiaozhang.autocomplete1;import android.app.Activity;import android.os.Bundle;import android.widget.CompoundButton;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.ImageView;import android.widget.ToggleButton;public class MainActivity extends Activity { private ImageView imageView; private ToggleButton togglebutton; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); imageView = (ImageView) findViewById(R.id.imageView); togglebutton = (ToggleButton) findViewById(R.id.togglebutton); togglebutton.setOnCheckedChangeListener(new OnCheckedChangeListener() { public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { imageView.setImageResource(isChecked ? R.drawable.right : R.drawable.wrong); } }); }}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:src="@drawable/wrong" /> <ToggleButton android:id="@+id/togglebutton" android:layout_width="120dp" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:textOff="wrong" android:textOn="right" /></LinearLayout>
