Android 动态申请定位权限

AndroidManifest.xml（清单文件）添加需要的权限

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <!-- 用于进行网络定位 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <!-- 用于访问GPS定位 -->
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /> <!-- 允许应用程序访问额外的位置提供命令 -->

//权限数组（申请定位）
private String[] permissions = new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_LOCATION_EXTRA_COMMANDS};

//返回code
private static final int OPEN_SET_REQUEST_CODE = 100;

//调用此方法判断是否拥有权限
private void initPermissions() {

    if (lacksPermission(permissions)) {//判断是否拥有权限
        //请求权限，第二参数权限String数据，第三个参数是请求码便于在onRequestPermissionsResult 方法中根据code进行判断
        ActivityCompat.requestPermissions(this, permissions, OPEN_SET_REQUEST_CODE);
    } else {
        //拥有权限执行操作
    }
}

//如果返回true表示缺少权限
public boolean lacksPermission(String[] permissions) {
    for (String permission : permissions) {
        //判断是否缺少权限，true=缺少权限
        if(ContextCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED){
            return true;
        }
    }
    return false;
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode){//响应Code
        case OPEN_SET_REQUEST_CODE:
            if (grantResults.length > 0) {
                for(int i = 0; i < grantResults.length; i++){
                    if(grantResults[i] != PackageManager.PERMISSION_GRANTED){
                        Toast.makeText(context,"未拥有相应权限",Toast.LENGTH_LONG).show();
                        return;
                    }
                }
                //拥有权限执行操作
            } else {
                Toast.makeText(context,"未拥有相应权限",Toast.LENGTH_LONG).show();
            }
            break;
    }
