Android(安卓)6.0动态权限及跳转GPS设置界面

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

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

@Overridepublic 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

name="notifyTitle">提示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。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。name="setting">设置name="cancel">取消

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();    }}@Overrideprotected 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 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 findDeniedPermissions(String[] permissions) {        List needRequestPermissonList = new ArrayList();        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
