Andriod 获取电池的信息实例代码

具体代码如下所示：

package com.example.yanlei.wifi;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.support.v7.app.AppCompatActivity;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;public class MainActivity extends AppCompatActivity {// 定义电池信息的按钮private Button btnBattery;// 定义显示电池信息的textview private TextView tvBattery;@Override public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);// 得到布局中的所有对象findView();// 设置对象的监听器setListener();}private void findView() {// 得到布局中的所有对象btnBattery = (Button) findViewById(R.id.btn_battery);tvBattery = (TextView) findViewById(R.id.tv_battery);}// 设置对象的监听器private void setListener() {btnBattery.setOnClickListener(listener);}OnClickListener listener = new OnClickListener() {@Override public void onClick(View v) {// TODO Auto-generated method stub switch (v.getId()) {// 当前的音量case R.id.btn_battery:IntentFilter filter = new IntentFilter();filter.addAction(Intent.ACTION_BATTERY_CHANGED);registerReceiver(mBroadcastReceiver, filter);break;}}};// 声明广播接受者对象private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {@Override public void onReceive(Context context, Intent intent) {// TODO Auto-generated method stub String action = intent.getAction();if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {// 得到电池状态：// BatteryManager.BATTERY_STATUS_CHARGING：充电状态。

// BatteryManager.BATTERY_STATUS_DISCHARGING：放电状态。

// BatteryManager.BATTERY_STATUS_NOT_CHARGING：未充满。

// BatteryManager.BATTERY_STATUS_FULL：充满电。

// BatteryManager.BATTERY_STATUS_UNKNOWN：未知状态。

int status = intent.getIntExtra("status", 0);// 得到健康状态：// BatteryManager.BATTERY_HEALTH_GOOD：状态良好。

// BatteryManager.BATTERY_HEALTH_DEAD：电池没有电。

// BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE：电池电压过高。

// BatteryManager.BATTERY_HEALTH_OVERHEAT：电池过热。

// BatteryManager.BATTERY_HEALTH_UNKNOWN：未知状态。

int health = intent.getIntExtra("health", 0);// boolean类型boolean present = intent.getBooleanExtra("present", false);// 得到电池剩余容量int level = intent.getIntExtra("level", 0);// 得到电池最大值。通常为100。

int scale = intent.getIntExtra("scale", 0);// 得到图标ID int icon_small = intent.getIntExtra("icon-small", 0);// 充电方式：　BatteryManager.BATTERY_PLUGGED_AC：AC充电。　BatteryManager.BATTERY_PLUGGED_USB：USB充电。

int plugged = intent.getIntExtra("plugged", 0);// 得到电池的电压int voltage = intent.getIntExtra("voltage", 0);// 得到电池的温度,0.1度单位。例如 表示197的时候，意思为19.7度int temperature = intent.getIntExtra("temperature", 0);// 得到电池的类型String technology = intent.getStringExtra("technology");// 得到电池状态String statusString = "";// 根据状态id，得到状态字符串switch (status) {case BatteryManager.BATTERY_STATUS_UNKNOWN:statusString = "unknown";break;case BatteryManager.BATTERY_STATUS_CHARGING:statusString = "charging";break;case BatteryManager.BATTERY_STATUS_DISCHARGING:statusString = "discharging";break;case BatteryManager.BATTERY_STATUS_NOT_CHARGING:statusString = "not charging";break;case BatteryManager.BATTERY_STATUS_FULL:statusString = "full";break;}//得到电池的寿命状态String healthString = "";//根据状态id，得到电池寿命switch (health) {case BatteryManager.BATTERY_HEALTH_UNKNOWN:healthString = "unknown";break;case BatteryManager.BATTERY_HEALTH_GOOD:healthString = "good";break;case BatteryManager.BATTERY_HEALTH_OVERHEAT:healthString = "overheat";break;case BatteryManager.BATTERY_HEALTH_DEAD:healthString = "dead";break;case BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE:healthString = "voltage";break;case BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE:healthString = "unspecified failure";break;}//得到充电模式String acString = "";//根据充电状态id，得到充电模式switch (plugged) {case BatteryManager.BATTERY_PLUGGED_AC:acString = "plugged ac";break;case BatteryManager.BATTERY_PLUGGED_USB:acString = "plugged usb";break;}//显示电池信息tvBattery.setText("电池的状态：" + statusString+ "\n健康值: "+ healthString+ "\n电池剩余容量： " + level+ "\n电池的最大值：" + scale+ "\n小图标：" + icon_small+ "\n充电方式：" + plugged+ "\n充电方式: " + acString+ "\n电池的电压：" + voltage+ "\n电池的温度：" + (float) temperature * 0.1+ "\n电池的类型：" + technology);}}};@Override protected void onPause() {super.onPause();// 解除注册监听unregisterReceiver(mBroadcastReceiver);}}以上所述是小编给大家介绍的Andriod 获取电池的信息实例代码，希望对大家有所帮助！
