查看的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了android电源信息查看方法。分享给大家供大家参考。具体如下:
1. PowerTestActivity:
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.BatteryManager;
import android.os.Bundle;
import android.os.PowerManager;
import android.view.View;
import android.widget.CheckBox;
import android.widget.TextView;
import java.text.DateFormat;
import java.util.Date;
/**
* So you thought sync used up your battery life.
*/
public class PowerTestActivity extends Activity {
TextView mLog;
DateFormat mDateFormat;
IntentFilter mFilter;
PowerManager.WakeLock mWakeLock;
SpinThread mThread;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set the layout for this activity. You can find it
// in res/layout/hello_activity.xml
setContentView(R.layout.main);
findViewById(R.id.checkbox).setOnClickListener(mClickListener);
mLog = (TextView)findViewById(R.id.log);
mDateFormat = DateFormat.getInstance();
mFilter = new IntentFilter();
mFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
mFilter.addAction(Intent.ACTION_BATTERY_LOW);
mFilter.addAction(Intent.ACTION_BATTERY_OKAY);
mFilter.addAction(Intent.ACTION_POWER_CONNECTED);
PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "BatteryWaster");
mWakeLock.setReferenceCounted(false);
}
@Override
public void onPause() {
stopRunning();
}
View.OnClickListener mClickListener = new View.OnClickListener() {
public void onClick(View v) {
CheckBox checkbox = (CheckBox)v;
if (checkbox.isChecked()) {
startRunning();
} else {
stopRunning();
}
}
};
void startRunning() {
log("Start");
registerReceiver(mReceiver, mFilter);
mWakeLock.acquire();
if (mThread == null) {
mThread = new SpinThread();
mThread.start();
}
}
void stopRunning() {
log("Stop");
unregisterReceiver(mReceiver);
mWakeLock.release();
if (mThread != null) {
mThread.quit();
