android电源信息查看(电量、温度、电压)实例代码

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;

public class PowerTestActivity extends Activity {
  TextView mLog;

  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
