简单实现 6.0权限

一
public void requestPermissions(int requestCode) {
try {
if (Build.VERSION.SDK_INT >= 23) {
ArrayList requestPerssionArr = new ArrayList<>();
int hasCamrea = checkSelfPermission(Manifest.permission.CAMERA);
if (hasCamrea != PackageManager.PERMISSION_GRANTED) {
requestPerssionArr.add(Manifest.permission.CAMERA);
}
int hasLocation = checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION);
if (hasLocation != PackageManager.PERMISSION_GRANTED) {
requestPerssionArr.add(Manifest.permission.ACCESS_FINE_LOCATION);
}

        int hasSdcardRead = checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE);
        if (hasSdcardRead != PackageManager.PERMISSION_GRANTED) {
            requestPerssionArr.add(Manifest.permission.READ_EXTERNAL_STORAGE);
        }

        int hasSdcardWrite = checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (hasSdcardWrite != PackageManager.PERMISSION_GRANTED) {
            requestPerssionArr.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        }

        int hasSdcards = checkSelfPermission(Manifest.permission.WRITE_SETTINGS);
        if (hasSdcards != PackageManager.PERMISSION_GRANTED) {
            requestPerssionArr.add(Manifest.permission.WRITE_SETTINGS);
        }

        int readPhoneState = checkSelfPermission(Manifest.permission.READ_PHONE_STATE);
        if (readPhoneState != PackageManager.PERMISSION_GRANTED) {
            requestPerssionArr.add(Manifest.permission.READ_PHONE_STATE);
        }
        // 是否应该显示权限请求 WRITE_SETTINGS
        if (requestPerssionArr.size() >= 1) {
            String[] requestArray = new String[requestPerssionArr.size()];
            for (int i = 0; i < requestArray.length; i++) {
                requestArray[i] = requestPerssionArr.get(i);
            }
            requestPermissions(requestArray, requestCode);
        }
    }
} catch (Exception e) {
    e.printStackTrace();
}

}

二

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
boolean flag = false;
for (int i = 0; i < permissions.length; i++) {
if (PackageManager.PERMISSION_GRANTED == grantResults[i]) {
flag = true;
}
}
}

记得在清单文件里面加权限
