今天小編就為大家分享一篇Android 6.0動(dòng)態(tài)權(quán)限及跳轉(zhuǎn)GPS設(shè)置界面的方法，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過來看看吧

1.動(dòng)態(tài)權(quán)限申請(qǐng)

模糊的位置信息android.permission.ACCESS_COARSE_LOCATION權(quán)限為例

在AndroidManifest文件中加入權(quán)限

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

然后java代碼中動(dòng)態(tài)申請(qǐng)

//動(dòng)態(tài)申請(qǐng)權(quán)限的測(cè)試方法
public void test() {
 // 要申請(qǐng)的權(quán)限 數(shù)組 可以同時(shí)申請(qǐng)多個(gè)權(quán)限
 String[] permissions = {Manifest.permission.ACCESS_COARSE_LOCATION};

 if (Build.VERSION.SDK_INT >= 23) {
  //如果超過6.0才需要?jiǎng)討B(tài)權(quán)限，否則不需要?jiǎng)討B(tài)權(quán)限
  //如果同時(shí)申請(qǐng)多個(gè)權(quán)限，可以for循環(huán)遍歷
  int check = ContextCompat.checkSelfPermission(this,permissions[0]);
  // 權(quán)限是否已經(jīng) 授權(quán) GRANTED---授權(quán) DINIED---拒絕
  if (check == PackageManager.PERMISSION_GRANTED) {
   //寫入你需要權(quán)限才能使用的方法
   run();
  } else {
   //手動(dòng)去請(qǐng)求用戶打開權(quán)限(可以在數(shù)組中添加多個(gè)權(quán)限) 1 為請(qǐng)求碼 一般設(shè)置為final靜態(tài)變量
   requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
  }
 } else {
  //寫入你需要權(quán)限才能使用的方法
  run();
 }
}

其中run()為你自己需要權(quán)限才能執(zhí)行的方法

然后重寫申請(qǐng)權(quán)限的回掉方法

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
          @NonNull int[] grantResults) {
 super.onRequestPermissionsResult(requestCode, permissions, grantResults);
 //回調(diào)，判斷用戶到底點(diǎn)擊是還是否。
 //如果同時(shí)申請(qǐng)多個(gè)權(quán)限，可以for循環(huán)遍歷
 if (requestCode == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
  //寫入你需要權(quán)限才能使用的方法
  run();
 } else {
  // 沒有獲取 到權(quán)限，從新請(qǐng)求，或者關(guān)閉app
  Toast.makeText(this,"需要獲得XXX權(quán)限",Toast.LENGTH_SHORT).show();
 }
}

2.跳轉(zhuǎn)GPS設(shè)置界面

相關(guān)字符串

<string name="notifyTitle">提示</string>
<string name="notifyMsg">當(dāng)前應(yīng)用缺少必要權(quán)限。\n\n請(qǐng)點(diǎn)擊\"設(shè)置\"-\"權(quán)限\"-打開所需權(quán)限。</string>
<string name="gpsNotifyMsg">當(dāng)前應(yīng)用需要打開定位功能。\n\n請(qǐng)點(diǎn)擊\"設(shè)置\"-\"定位服務(wù)\"-打開定位功能。</string>
<string name="setting">設(shè)置</string>
<string name="cancel">取消</string>

java代碼

private int GPS_REQUEST_CODE = 10;

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

/**
 * 跳轉(zhuǎn)GPS設(shè)置
 */
private void openGPSSettings() {
 if (checkGPSIsOpen()) {
  initLocation(); //自己寫的定位方法
 } else {
  //沒有打開則彈出對(duì)話框
  new AlertDialog.Builder(this)
    .setTitle(R.string.notifyTitle)
    .setMessage(R.string.gpsNotifyMsg)
    // 拒絕, 退出應(yīng)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) {
        //跳轉(zhuǎn)GPS設(shè)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，比如再次檢測(cè)是否打開GPS了 或者定位
  openGPSSettings();
 }
}

最后在需要的地方調(diào)用 openGPSSettings()方法。

效果（是在相關(guān)權(quán)限是已經(jīng)申請(qǐng)好的情況下的效果）

3.下面是我在高德地圖Demo中看見的檢測(cè)權(quán)限的Activity

public class CheckPermissionsActivity extends Activity implements
  ActivityCompat.OnRequestPermissionsResultCallback {
 /**
  * 需要進(jìn)行檢測(cè)的權(quán)限數(shù)組
  */
 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;

 /**
  * 判斷是否需要檢測(cè)，防止不停的彈框
  */
 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);
  }
 }

 /**
  * 獲取權(quán)限集中需要申請(qǐng)權(quán)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;
 }

 /**
  * 檢測(cè)是否說有的權(quán)限都已經(jīng)授權(quán)
  *
  * @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;
   }
  }
 }

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

  // 拒絕, 退出應(yīng)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();
 }

 /**
  * 啟動(dòng)應(yīng)用的設(shè)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);
  }
 }
}

繼承于CheckPermissionsActivity即可

不允許就跳轉(zhuǎn)系統(tǒng)設(shè)置界面，若沒設(shè)置再次檢測(cè)權(quán)限并申請(qǐng)，直到允許為止。可和GPS設(shè)置搭配使用
