【Android】Android6.0+ 动态申请权限

Android 6.0+ （SDK 版本号大于23后）对于普通权限可以在AndroidMinifest.xml文件中可以直接使用，而对于那些危险权限（如：定位权限，通话，发送短信等）需要动态申请权限；

下面是一个通过高德定位的案例

MainActivity中：

    //初始化定位    private void initLocation(){    //初始化定位    mLocationClient = new AMapLocationClient(getApplicationContext());    //设置定位回调监听    mLocationClient.setLocationListener(new AMapLocationListener() {        @Override        public void onLocationChanged(AMapLocation aMapLocation) {            if (aMapLocation != null) {                // 0为成功                if (aMapLocation.getErrorCode() == 0) {                    Toast.makeText(MainActivity.this, aMapLocation.getProvince()+" "+aMapLocation.getCity()+" "+aMapLocation.getDistrict(), Toast.LENGTH_SHORT).show();                    StopLocation();                }else{                    if(aMapLocation.getErrorCode()==12)                        Toast.makeText(MainActivity.this, "您没有授予定位所需权限，请到授权管理允许权限！", Toast.LENGTH_SHORT).show();                    else                        Toast.makeText(MainActivity.this, "错误代码"+aMapLocation.getErrorCode(), Toast.LENGTH_SHORT).show();                }            }        }    });    //初始化定位参数    mLocationOption = new AMapLocationClientOption();    //设置定位模式为高精度模式，Battery_Saving为低功耗模式，Device_Sensors是仅设备模式    mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);    //设置是否返回地址信息（默认返回地址信息）    mLocationOption.setNeedAddress(true);    //是否只定位一次    mLocationOption.setOnceLocation(true);    //设置是否强制刷新WIFI，默认为强制刷新    mLocationOption.setWifiScan(true);    //设置是否允许模拟位置,默认为false，不允许模拟位置    mLocationOption.setMockEnable(false);    //设置定位间隔,单位毫秒,默认为2000ms    mLocationOption.setInterval(2000);    //给定位客户端对象设置定位参数    mLocationClient.setLocationOption(mLocationOption);    //启动定位    mLocationClient.startLocation();    }    //开始定位    private void startLocation(){        mLocationClient.startLocation();    }    //结束定位    private void StopLocation(){        mLocationClient.stopLocation();    }
