android设置gps自动开启

1.第一种方法

private void toggleGPS() {
            Intent gpsIntent = new Intent();
            gpsIntent.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
            gpsIntent.addCategory("android.intent.category.ALTERNATIVE");
            gpsIntent.setData(Uri.parse("custom:3"));
            try {
                    PendingIntent.getBroadcast(StartActivity.this, 0, gpsIntent, 0).send();
            } catch (CanceledException e) {
                    e.printStackTrace();
            }
    }
 

2.第二种方法
   private void openGPSSettings() {       
      //获取GPS现在的状态(打开或是关闭状态)
    boolean gpsEnabled = Settings.Secure.isLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER );
 
    if(gpsEnabled)
    {

    //关闭GPS
     Settings.Secure.setLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER, false );
    }
    else
    {
     //打开GPS  www.zzzyk.com
     Settings.Secure.setLocationProviderEnabled( getContentResolver(), LocationManager.GPS_PROVIDER, true);

    }
   
 3.第三种方法(手动设置)

     LocationManager alm = (LocationManager)StartActivity.this.getSystemService(Context.LOCATION_SERVICE);       
       if (alm.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER))
       {           
        Toast.makeText(this, "GPS模块正常", Toast.LENGTH_SHORT).show();
       }       
      
       Toast.makeText(this, "请开启GPS!", Toast.LENGTH_SHORT).show();
       Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);
       startActivityForResult(intent,0); //此为设置完成后返回到获取界面  
   
 第一第二种需要加上权限

  <!--允许程序读取或写入系统设置 -->
 <uses-permission android:name="android.permission.WRITE_SETTINGS" ></uses-permission>
 <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
