使用方法
注意：如果轮子死活下载不下来，说明maven地址有毛病，你需要找到jitpack的官网首页，查看最新的官网地址
3.调用方式( 必须在UI线程使用)：
OnPermissionCallback 中可以override授权对框框和样式
注意：记得去gayhub查看最新版本，最新版本最niubility
1.全部允许 2.拒绝 3.拒绝 4.用户拒绝并且选中了不再询问，弹窗让用户去授权 5.用户同意了授权，闲的难受去关闭了授权
实现原理：
源码：
欢迎联系、指正、批评
1.工程目录下的build.gradle中添加代码：
allprojects {
repositories {
maven { url 'https://www.jitpack.io' }
}
}2.直接在需要使用的模块的build.gradle中添加代码：
api 'com.github.AnJiaoDe:PermissionNiubility:V1.0.8'可以一个个请求：
PermissionUtils.checkPermission(MainActivity.this,
new String[]{Manifest.permission.CAMERA},
new OnPermissionCallback(MainActivity.this) {
@Override
public void onPermissionHave() {
PermissionUtils.checkPermission(MainActivity.this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
new OnPermissionCallback(MainActivity.this) {
@Override
public void onPermissionHave() {
}
});
}
});也可以同时请求：
PermissionUtils.checkPermission(MainActivity.this,
new String[]{Manifest.permission.CAMERA,
Manifest.permission.WRITE_EXTERNAL_STORAGE},
new OnPermissionCallback(MainActivity.this) {
@Override
public void onPermissionHave() {
}
});public abstract class OnPermissionCallback {
private Activity activity;
public OnPermissionCallback(Activity activity) {
this.activity = activity;
}
public abstract void onPermissionHave();
public void onPermissionRefuse() {
}
public void onPermissionRefuseNoAsk() {
authorize();
}
public String getAuthorizeDialogButtonPositive() {
return "去授权";
}
public String getAuthorizeDialogMessage() {
return "禁用这些权限，您可能无法使用某些功能";
}
public String getAuthorizeDialogButtonNegative() {
return "取消";
}
public void authorize() {
//解释原因，并且引导用户至设置页手动授权
new AlertDialog.Builder(activity)
.setMessage(getAuthorizeDialogMessage())
.setPositiveButton(getAuthorizeDialogButtonPositive(), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//引导用户至设置页手动授权
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", activity.getPackageName(), null);
intent.setData(uri);
activity.startActivity(intent);
}
})
.setNegativeButton(getAuthorizeDialogButtonNegative(), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//引导用户手动授权，权限请求失败
}
}).show();
}
}Android 6.0以上，危险权限必须经过动态请求，危险权限分组图
启动一个全透明的Activity去请求权限，回调对象用单例类持有
PermissionUtils：
public class PermissionUtils {
public static void checkPermission(Activity activity, String[] permissions, OnPermissionCallback callbackPermission) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
PermissionManager.getInstance().getListCallback().add(callbackPermission);
Intent intent = new Intent(activity, PermissionActivity.class);
Bundle bundle = new Bundle();
bundle.putStringArray(PermissionManager.BUNDLE_KEY_PERMISSIONS, permissions);
intent.putExtra(PermissionManager.INTENT_KEY_PERMISSIONS, bundle);
activity.startActivity(intent);
return;
}
}
callbackPermission.onPermissionHave();
}
}PermissionActivity:
public class PermissionActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setStatusBarColor(Color.TRANSPARENT);
getWindow().setNavigationBarColor(Color.TRANSPARENT);
Bundle bundle = getIntent().getBundleExtra(PermissionManager.INTENT_KEY_PERMISSIONS);
String[] permissions = null;
if (bundle != null)
permissions = bundle.getStringArray(PermissionManager.BUNDLE_KEY_PERMISSIONS);
if (permissions != null && permissions.length > 0)
ActivityCompat.requestPermissions(this, permissions, 1001);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
OnPermissionCallback callbackPermission = null;
List<OnPermissionCallback> list = PermissionManager.getInstance().getListCallback();
if (!list.isEmpty()) callbackPermission = list.remove(list.size() - 1);
for (int i = 0; i < permissions.length; i++) {
if (grantResults[i] == PackageManager.PERMISSION_GRANTED) continue;
if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
//在用户已经拒绝授权的情况下，如果shouldShowRequestPermissionRationale返回false则
// 可以推断出用户选择了“不在提示”选项，在这种情况下需要引导用户至设置页手动授权
if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permissions[i])) {
finish();
if (callbackPermission != null)
callbackPermission.onPermissionRefuseNoAsk();
} else {
finish();
//权限请求失败，但未选中“不再提示”选项
if (callbackPermission != null)
callbackPermission.onPermissionRefuse();
}
return;
}
}
finish();
if (callbackPermission != null)
callbackPermission.onPermissionHave();
}
}
OnPermissionCallback：
public abstract class OnPermissionCallback {
private Activity activity;
public OnPermissionCallback(Activity activity) {
this.activity = activity;
}
public abstract void onPermissionHave();
public void onPermissionRefuse() {
}
public void onPermissionRefuseNoAsk() {
authorize();
}
public String getAuthorizeDialogButtonPositive() {
return "去授权";
}
public String getAuthorizeDialogMessage() {
return "禁用这些权限，您可能无法使用某些功能";
}
public String getAuthorizeDialogButtonNegative() {
return "取消";
}
public void authorize() {
//解释原因，并且引导用户至设置页手动授权
new AlertDialog.Builder(activity)
.setMessage(getAuthorizeDialogMessage())
.setPositiveButton(getAuthorizeDialogButtonPositive(), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//引导用户至设置页手动授权
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", activity.getPackageName(), null);
intent.setData(uri);
activity.startActivity(intent);
}
})
.setNegativeButton(getAuthorizeDialogButtonNegative(), new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//引导用户手动授权，权限请求失败
}
}).show();
}
}
PermissionManager：
class PermissionManager {
public static final String INTENT_KEY_PERMISSIONS = "intent_key_permissions";
public static final String BUNDLE_KEY_PERMISSIONS = "bundle_key_permissions";
private List<OnPermissionCallback> listCallback;
private PermissionManager() {
listCallback=new ArrayList<>();
}
private static class PermissionManagerHolder {
private static PermissionManager instance = new PermissionManager();
}
public static PermissionManager getInstance() {
return PermissionManagerHolder.instance;
}
public List<OnPermissionCallback> getListCallback() {
return listCallback;
}
}
