一、集成三方库PermissionsDispatcher
1.添加依赖
a. project目录下的build.gradle文件
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
-
compile 'com.github.hotchemi:permissionsdispatcher:2.2.0'
-
apt 'com.github.hotchemi:permissionsdispatcher-processor:2.2.0'
2.给Activity或者Fragment注册
-
@RuntimePermissions
-
public class LoginActivity extends AppCompatActivity{
3.实现五个方法
-
/**
-
* 处理当用户允许该权限时需要处理的方法（括号里面是当前需要请求的权限）
-
*/
-
@NeedsPermission(Manifest.permission.READ_PHONE_STATE)
-
void doACacheNeedsPermission() {
-
//do something
-
}
-
@OnShowRationale(Manifest.permission.READ_PHONE_STATE)
-
void ACacheShowRationale(PermissionRequest request) {
-
request.proceed(); // 提示用户权限使用的对话框
-
}
-
-
@OnNeverAskAgain(Manifest.permission.READ_PHONE_STATE)
-
void ACacheOnNeverAskAgain() {
-
new AlertDialog.Builder(this)
-
.setPositiveButton("重新设置", new DialogInterface.OnClickListener() {
-
@Override
-
public void onClick(@NonNull DialogInterface dialog, int which) {
-
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
-
intent.setData(Uri.parse("package:" + getPackageName()));
-
startActivity(intent);
-
}
-
})
-
.setNegativeButton("取消", null)
-
.setCancelable(false)
-
.setMessage("您已拒绝授予权限")
-
.show();
-
}
-
-
/**
-
* 如果用户拒绝该权限执行的方法
-
*/
-
@OnPermissionDenied(Manifest.permission.READ_PHONE_STATE)
-
void ACacheOnPermissionDenied() {
-
MyUtil.showToast("真的确定拒绝授予权限吗");
-
}
-
/**
-
* 权限请求回调，提示用户之后，用户点击“允许”或者“拒绝”之后调用此方法
-
* @param requestCode 定义的权限编码
-
* @param permissions 权限名称
-
* @param grantResults 允许/拒绝
-
*/
-
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
-
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
-
LoginActivityPermissionsDispatcher.onRequestPermissionsResult(this, requestCode, grantResults);
-
}
比如是一个点击事件
-
case R.id.btn:
-
//6.0权限
-
LoginActivityPermissionsDispatcher.doACacheNeedsPermissionWithCheck(this);
-
break;
二、Android6.0M权限管理实战,完美轻量级封装
1.第一步：检测所有的权限是否都已授权
-
/**
-
* 检测所有的权限是否都已授权
-
*
-
* @param permissions
-
* @return
-
*/
-
private boolean checkPermissions(String[] permissions) {
-
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
-
return true;
-
}
-
-
for (String permission : permissions) {
-
if (ContextCompat.checkSelfPermission(this, permission) !=
-
PackageManager.PERMISSION_GRANTED) {
-
return false;
-
}
-
}
-
return true;
-
}
2.第二步：获取权限集中需要申请权限的列表
-
/**
-
* 获取权限集中需要申请权限的列表
-
*
-
* @param permissions
-
* @return
-
*/
-
private List<String> getDeniedPermissions(String[] permissions) {
-
List<String> needRequestPermissionList = new ArrayList<>();
-
for (String permission : permissions) {
-
if (ContextCompat.checkSelfPermission(this, permission) !=
-
PackageManager.PERMISSION_GRANTED ||
-
ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {
-
needRequestPermissionList.add(permission);
-
}
-
}
-
return needRequestPermissionList;
-
}
-
/**
-
* 请求权限
-
*
-
* @param permissions 请求的权限
-
* @param requestCode 请求权限的请求码
-
*/
-
public void requestPermission(String[] permissions, int requestCode) {
-
this.REQUEST_CODE_PERMISSION = requestCode;
-
if (checkPermissions(permissions)) {
-
permissionSuccess(REQUEST_CODE_PERMISSION);
-
} else {
-
List<String> needPermissions = getDeniedPermissions(permissions);
-
ActivityCompat.requestPermissions(this, needPermissions.toArray(new String[needPermissions.size()]), REQUEST_CODE_PERMISSION);
-
}
-
}
-
/**
-
* 系统请求权限回调
-
*
-
* @param requestCode
-
* @param permissions
-
* @param grantResults
-
*/
-
@Override
-
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
-
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
-
if (requestCode == REQUEST_CODE_PERMISSION) {
-
if (verifyPermissions(grantResults)) {
-
permissionSuccess(REQUEST_CODE_PERMISSION);
-
} else {
-
permissionFail(REQUEST_CODE_PERMISSION);
-
showTipsDialog();
-
}
-
}
-
}
-
/**
-
* 确认所有的权限是否都已授权
-
*
-
* @param grantResults
-
* @return
-
*/
-
private boolean verifyPermissions(int[] grantResults) {
-

-
return false;
-
}
-

-
return true;
-
}

-
*/
-

-
}
-

*/
-
public void permissionFail(int requestCode) {
