android实现充电时电量变化

监控电池变化比较简单，但是充电时候要电量从当前电量增长到满状态，然后一直重复，后来发现将对应的ImageView的background指定到animation即可

 

1.需要多张电量图片

电量状态1
电量状态2
 
电量状态3
 
 
电量状态4

电量状态5
 
电量状态6

 

2.然后生成多个animation文件，分别是从状态1到状态6，状态2到状态6.。。。。。

 

    如：animation_battery_1.xml

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
	android:oneshot="false">
	<item android:drawable="@drawable/battery_1" android:duration="200" />
	<item android:drawable="@drawable/battery_2" android:duration="200" />
	<item android:drawable="@drawable/battery_3" android:duration="200" />
	<item android:drawable="@drawable/battery_4" android:duration="200" />
	<item android:drawable="@drawable/battery_5" android:duration="200" />
	<item android:drawable="@drawable/battery_6" android:duration="200" />
</animation-list>

 

   如：animation_battery_2.xml

<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
	android:oneshot="false">
	<item android:drawable="@drawable/battery_2" android:duration="200" />
	<item android:drawable="@drawable/battery_3" android:duration="200" />
	<item android:drawable="@drawable/battery_4" android:duration="200" />
	<item android:drawable="@drawable/battery_5" android:duration="200" />
	<item android:drawable="@drawable/battery_6" android:duration="200" />
</animation-list>

 

3.在代码里面通过设置ivBattery.setBackgroundResource(batteryAnimation)，其中batteryAnimation为animation文件

public class BatteryActivity extends Activity {

	ImageView ivBattery;//电池电量
	ImageView ivBatteryCharging;//充电中
	
	TextView tvStatus;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		setContentView(R.layout.battery_charging);
		
		ivBattery = (ImageView)findViewById(R.id.iv_battry);
		ivBatteryCharging = (ImageView)findViewById(R.id.iv_battry_charging);
		tvStatus = (TextView)findViewById(R.id.tv_statues);
		
		registerReceiver(batteryReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
	}
	
	@Override
	protected void onDestroy() {
		super.onDestroy();
		unregisterReceiver(batteryReceiver);
	}
	
	private BroadcastReceiver batteryReceiver = new BroadcastReceiver() {
		
		@Override
		public void onReceive(Context context, Intent intent) {
			if(intent.getAction().equals(Intent.ACTION_BATTERY_CHANGED)){
				int level = intent.getIntExtra("level", 0);
				int scale = intent.getIntExtra("scale", 100);
				int status = intent.getIntExtra("status", BatteryManager.BATTERY_STATUS_NOT_CHARGING);
				
				notifyBattery(level,scale,status);
			}
		}
	};
	
	
	public void notifyBattery(int level,int scale,int status){
		
		int per = scale/6;
		int batteryPic;//电量图片
		int batteryAnimation;//电量动态增长
		if(level<per){
			batteryAnimation = R.drawable.animation_battery_1;
			batteryPic = R.drawable.battery_1;
		}else if(level<per*2){
			batteryAnimation = R.drawable.animation_battery_2;
			batteryPic = R.drawable.battery_2;
		}else if(level<per*3){
			batteryAnimation = R.drawable.animation_battery_3;
			batteryPic = R.drawable.battery_3;
		}else if(level<per*4){
			batteryAnimation = R.drawable.animation_battery_4;
			batteryPic = R.drawable.battery_4;
		}else if(level<per*5){
			batteryAnimation = R.drawable.animation_battery_5;
			batteryPic = R.drawable.battery_5;
		}else{
			batteryAnimation = R.drawable.animation_battery_5;
			batteryPic = R.drawable.battery_6;
		}
		
		if(status==BatteryManager.BATTERY_STATUS_CHARGING){
			ivBattery.setBackgroundResource(batteryAnimation);//將電量背景修改為animation即可
			AnimationDrawable frameAnimation = (AnimationDrawable)ivBattery.getBackground();
			if(!frameAnimation.isRunning()){
				frameAnimation.stop();
				frameAnimation.start();
			}
			ivBatteryCharging.setVisibility(View.VISIBLE);
			
			tvStatus.setText("充电中，电量背景为animation");
		}else{
			ivBatteryCharging.setVisibility(View.INVISIBLE);
			
			ivBattery.setBackgroundResource(batteryPic);
			tvStatus.setText("没有充电，电量背景为图片");
		}
	}
}

 

 4.记得在manifest中添加权限

 

 <uses-permission android:name="android.permission.BATTERY_STATS"/>

 

 5.充电的时候界面显示，其中图片是动态的

 
   

 

6.没有充电时候显示

7。其他图片

 

电池背景图片

 充电的时候显示闪电
