عرض حالة البطارية في تطبيق اندرويد برمجياً

بسم الله الرحمن الرحيم

كيفية عرض حالة البطارية + هل الشاحن موصول في الجهاز, برمجياً في تطبيق اندرويد.

قم بإنشاء تطبيق جديد, وأنسخ الأكواد التالية :

main.xml

<LinearLayout android:layout_height="match_parent" 
    android:layout_width="match_parent" 
    android:orientation="vertical"
    tools:context=".Main" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_margin="30dp">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:layout_gravity="center" >

        <TextView
            android:id="@+id/tv_percentage"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#ff0000"
            android:textColor="#000"
            android:textSize="20sp"
            android:text="مجهولة" />
        

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:text="نسبة الشحن : " />
    </LinearLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:layout_gravity="center" >

        <TextView
            android:id="@+id/tv_state"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:text="نعم" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:text="الشاحن موصول : " />
    </LinearLayout>
 
</LinearLayout>

 Main.java

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.view.Menu;
import android.widget.TextView;
 
public class Main extends Activity {
 
 TextView batteryPercent, ChargingState;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  batteryPercent = (TextView) findViewById(R.id.tv_percentage);
  ChargingState = (TextView) findViewById(R.id.tv_state);
  getBatteryPercentage();
  if(isPhonePluggedIn(getApplicationContext()).compareToIgnoreCase("نعم")== 0)
  {
   ChargingState.setText("نعم");
  }
  else
   ChargingState.setText("لا");
   
 }
 
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }
 
 private void getBatteryPercentage() {
   
   
  BroadcastReceiver batteryLevel = new BroadcastReceiver() {
    
   public void onReceive(Context context, Intent intent) {
    context.unregisterReceiver(this);
    int currentLevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
    int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
    int level= -1;
    if (currentLevel >= 0 && scale > 0) {
     level = (currentLevel * 100) / scale;
    }
    batteryPercent.setText(level + "%");
   }
  };
   
  IntentFilter batteryLevelFilter = new IntentFilter(
    Intent.ACTION_BATTERY_CHANGED);
  registerReceiver(batteryLevel, batteryLevelFilter);
   
 }
 
 public static String isPhonePluggedIn(Context context) {
  boolean charging = false;
  String result = "لا";
  final Intent batteryIntent = context.registerReceiver(null,
    new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
  int status = batteryIntent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
  boolean batteryCharge = status == BatteryManager.BATTERY_STATUS_CHARGING;
 
  int chargePlug = batteryIntent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
  boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
  boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;
 
  if (batteryCharge)
   charging = true;
  if (usbCharge)
   charging = true;
  if (acCharge)
   charging = true;
 
  if (charging){
   result = "نعم";
    
  }
  return result;
 }
}

أفتح ملف AndroidManifest.xml واعطي التطبيق الصلاحيات التالية :

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

معاينة:
