网上打开与关闭gps几种方案测试，其中方案3可行

       对于网上提到的几种开启或者关闭GPS方案，分别进行了测试，开发环境android 7.0，时间202007；

其中方案1和2，成功；方案3，成功；

方案1：（失败）

    // 这段代码可以实现GPS开关状态的切换-经过测试不行；20200722
//        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(MainActivity.this, 0, GPSIntent, 0).send();
//        } catch (PendingIntent.CanceledException e) {
//            e.printStackTrace();
//        }
//        try {
//            Thread.sleep(2000);
//        } catch (InterruptedException e) {
//            e.printStackTrace();
//        }

方案2：（失败）

Settings.Secure.setLocationProviderEnabled(getContentResolver(), LocationManager.GPS_PROVIDER, true);

在权限添加这里卡住，提示需要在系统-app目录下；

<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

方案3：（可以）

 

//开启GPS
public static final String GPS_ON = "settings put secure location_providers_allowed +gps";
    
//关闭GPS
public static final String GPS_OFF = "settings put secure location_providers_allowed -gps";
 
//查看GPS状态
public static final String QUERY_GPS_STATE = "settings get secure location_providers_allowed";

private void toggleGPS(String cmd){
    //Runtime对象
    Runtime runtime = Runtime.getRuntime();
    OutputStream localOutputStream=null;
    DataOutputStream localDataOutputStream=null;

    try {
        Process localProcess = runtime.exec("su");
        localOutputStream = localProcess.getOutputStream();
        localDataOutputStream = new DataOutputStream(localOutputStream);
        localDataOutputStream.writeBytes(cmd);
        localDataOutputStream.flush();
        Log.e(TAG,"执行命令"+cmd);
    } catch (IOException e) {
        //MyLog.e(TAG+"strLine:"+e.getMessage());
        e.printStackTrace();
    }finally {
        if(localDataOutputStream!= null){
            try {
                localDataOutputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        if(localOutputStream!= null){
            try {
                localOutputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
