1.动态权限申请

模糊的位置信息android.permission.ACCESS_COARSE_LOCATION权限为例

在AndroidManifest文件中加入权限

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

然后java代码中动态申请

//动态申请权限的测试方法
public void test() {
 // 要申请的权限 数组 可以同时申请多个权限
 String[] permissions = {Manifest.permission.ACCESS_COARSE_LOCATION};

 if (Build.VERSION.SDK_INT >= 23) {
  //如果超过6.0才需要动态权限，否则不需要动态权限
  //如果同时申请多个权限，可以for循环遍历
  int check = ContextCompat.checkSelfPermission(this,permissions[0]);
  // 权限是否已经 授权 GRANTED---授权 DINIED---拒绝
  if (check == PackageManager.PERMISSION_GRANTED) {
   //写入你需要权限才能使用的方法
   run();
  } else {
   //手动去请求用户打开权限(可以在数组中添加多个权限) 1 为请求码 一般设置为final静态变量
   requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
  }
 } else {
  //写入你需要权限才能使用的方法
  run();
 }
}

其中run()为你自己需要权限才能执行的方法

然后重写申请权限的回掉方法

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
          @NonNull int[] grantResults) {
 super.onRequestPermissionsResult(requestCode, permissions, grantResults);
 //回调，判断用户到底点击是还是否。
 //如果同时申请多个权限，可以for循环遍历
 if (requestCode == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
  //写入你需要权限才能使用的方法
  run();
 } else {
  // 没有获取 到权限，从新请求，或者关闭app
  Toast.makeText(this,"需要获得XXX权限",Toast.LENGTH_SHORT).show();
 }
}

2.跳转GPS设置界面

相关字符串

<string name="notifyTitle">提示</string>
<string name="notifyMsg">当前应用缺少必要权限。\n\n请点击\"设置\"-\"权限\"-打开所需权限。</string>
<string name="gpsNotifyMsg">当前应用需要打开定位功能。\n\n请点击\"设置\"-\"定位服务\"-打开定位功能。</string>
<string name="setting">设置</string>
<string name="cancel">取消</string>

java代码

private int GPS_REQUEST_CODE = 10;

/**
 * 检测GPS是否打开
 *
 * @return
 */
private boolean checkGPSIsOpen() {
 boolean isOpen;
 LocationManager locationManager = (LocationManager) this
   .getSystemService(Context.LOCATION_SERVICE);
 isOpen = locationManager.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER);
 return isOpen;
}

/**
 * 跳转GPS设置
 */
private void openGPSSettings() {
 if (checkGPSIsOpen()) {
  initLocation(); //自己写的定位方法
 } else {
  //没有打开则弹出对话框
  new AlertDialog.Builder(this)
    .setTitle(R.string.notifyTitle)
    .setMessage(R.string.gpsNotifyMsg)
    // 拒绝, 退出应用
    .setNegativeButton(R.string.cancel,
      new DialogInterface.OnClickListener() {
       @Override
       public void onClick(DialogInterface dialog, int which) {
        finish();
       }
      })

    .setPositiveButton(R.string.setting,
      new DialogInterface.OnClickListener() {
       @Override
       public void onClick(DialogInterface dialog, int which) {
        //跳转GPS设置界面
        Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
        startActivityForResult(intent, GPS_REQUEST_CODE);
       }
      })

    .setCancelable(false)
    .show();

 }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 super.onActivityResult(requestCode, resultCode, data);
 if (requestCode == GPS_REQUEST_CODE) {
  //做需要做的事情，比如再次检测是否打开GPS了 或者定位
  openGPSSettings();
 }
}

最后在需要的地方调用 openGPSSettings()方法。

效果（是在相关权限是已经申请好的情况下的效果）

3.下面是我在高德地图Demo中看见的检测权限的Activity

public class CheckPermissionsActivity extends Activity implements
  ActivityCompat.OnRequestPermissionsResultCallback {
 /**
  * 需要进行检测的权限数组
  */
 protected String[] needPermissions = {
   Manifest.permission.ACCESS_COARSE_LOCATION,
   Manifest.permission.ACCESS_FINE_LOCATION,
   Manifest.permission.WRITE_EXTERNAL_STORAGE,
   Manifest.permission.READ_EXTERNAL_STORAGE,
   Manifest.permission.READ_PHONE_STATE
 };

 private static final int PERMISSON_REQUESTCODE = 0;
 private static final int SETTING_REQUESTCODE = 1;

 /**
  * 判断是否需要检测，防止不停的弹框
  */
 private boolean isNeedCheck = true;

 @Override
 protected void onResume() {
  super.onResume();
  if (isNeedCheck) {
   checkPermissions(needPermissions);
  }
 }

 /**
  * @param permissions
  * @since 2.5.0
  */
 private void checkPermissions(String... permissions) {
  List<String> needRequestPermissonList = findDeniedPermissions(permissions);
  if (null != needRequestPermissonList
    && needRequestPermissonList.size() > 0) {
   ActivityCompat.requestPermissions(this,
     needRequestPermissonList.toArray(
       new String[needRequestPermissonList.size()]),
     PERMISSON_REQUESTCODE);
  }
 }

 /**
  * 获取权限集中需要申请权限的列表
  *
  * @param permissions
  * @return
  * @since 2.5.0
  */
 private List<String> findDeniedPermissions(String[] permissions) {
  List<String> needRequestPermissonList = new ArrayList<String>();
  for (String perm : permissions) {
   if (ContextCompat.checkSelfPermission(this,
     perm) != PackageManager.PERMISSION_GRANTED
     || ActivityCompat.shouldShowRequestPermissionRationale(
     this, perm)) {
    needRequestPermissonList.add(perm);
   }
  }
  return needRequestPermissonList;
 }

 /**
  * 检测是否说有的权限都已经授权
  *
  * @param grantResults
  * @return
  * @since 2.5.0
  */
 private boolean verifyPermissions(int[] grantResults) {
  for (int result : grantResults) {
   if (result != PackageManager.PERMISSION_GRANTED) {
    return false;
   }
  }
  return true;
 }

 @Override
 public void onRequestPermissionsResult(int requestCode,
           String[] permissions, int[] paramArrayOfInt) {
  if (requestCode == PERMISSON_REQUESTCODE) {
   if (!verifyPermissions(paramArrayOfInt)) {
    showMissingPermissionDialog();
    isNeedCheck = false;
   }
  }
 }

 /**
  * 显示提示信息
  *
  * @since 2.5.0
  */
 private void showMissingPermissionDialog() {
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
  builder.setTitle(R.string.notifyTitle);
  builder.setMessage(R.string.notifyMsg);

  // 拒绝, 退出应用
  builder.setNegativeButton(R.string.cancel,
    new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, int which) {
      finish();
     }
    });

  builder.setPositiveButton(R.string.setting,
    new DialogInterface.OnClickListener() {
     @Override
     public void onClick(DialogInterface dialog, int which) {
      startAppSettings();
     }
    });

  builder.setCancelable(false);

  builder.show();
 }

 /**
  * 启动应用的设置
  *
  * @since 2.5.0
  */
 private void startAppSettings() {
  Intent intent = new Intent(
    Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
  intent.setData(Uri.parse("package:" + getPackageName()));
  startActivityForResult(intent, SETTING_REQUESTCODE);
 }

 @Override
 public boolean onKeyDown(int keyCode, KeyEvent event) {
  if (keyCode == KeyEvent.KEYCODE_BACK) {
   this.finish();
   return true;
  }
  return super.onKeyDown(keyCode, event);
 }

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  if (requestCode == SETTING_REQUESTCODE) {
   checkPermissions(needPermissions);
  }
 }
}

继承于CheckPermissionsActivity即可

不允许就跳转系统设置界面，若没设置再次检测权限并申请，直到允许为止。可和GPS设置搭配使用
