权限的适配主要就是两步，一是请求权限，二是系统应答，主要在这两个地方进行封装。主要使用第三方库PermissionsDispatcher

（1）项目build.gradle 中添加
classpath ‘com.neenbedankt.gradle.plugins:android-apt:1.8’
（2）app的 build.gradle 中添加
apply plugin:’android-apt’
apt ‘com.github.hotchemi:permissionsdispatcher-processor:2.1.3’

1.定义PermissionHandler用于权限回调，权限通过、权限拒绝、权限不再询问三种情况

public abstract class PermissionHandle{//权限通过public abstract void onGranted();//权限拒绝public abstract void onDenied();//权限不在询问public boolean onNeverAsk(){return false;}}

2、请求权限

private PermissionHandle mHandle;/*** 请求权限* @param permissions 权限列表* @param handle 回调*/protected void requestPermission(String[] permissions,PermissionHandle handle){if (PermissionUtil.hasSelfPermissions(this,permissions)){handle.onGranted();}else{mHandle=handle;ActivityCompat.requestPermissions(this,permissions,001);}}

注：PermissionUtil是PermissionsDispatcher中使用的工具类

public final class PermissionUtil {private static SimpleArrayMap<String,Integer> MIN_SDK_PERMISSIONS;static {MIN_SDK_PERMISSIONS=new SimpleArrayMap<>(8);MIN_SDK_PERMISSIONS.put("com.android.voicemail.permission.ADD_VOICEMAIL",14);MIN_SDK_PERMISSIONS.put("android.permission.BODY_SENSORS",20);MIN_SDK_PERMISSIONS.put("android.permission.READ_CALL_LOG",16);MIN_SDK_PERMISSIONS.put("android.permission.READ_EXTERNAL_STORAGE",16);MIN_SDK_PERMISSIONS.put("android.permission.USE_SIP",9);MIN_SDK_PERMISSIONS.put("android.permission.WRITE_CALL_LOG",16);MIN_SDK_PERMISSIONS.put("android.permission.SYSTEM_ALERT_WINDOW", 23);MIN_SDK_PERMISSIONS.put("android.permission.WRITE_SETTINGS", 23);}private static volatile int targetSdkVersion=-1;public PermissionUtil() {}//检查所有的权限是否被授权public static boolean verifyPermissions(int... grantResults){if (grantResults.length==0){return false;}for (int result : grantResults) {if (result!= PackageManager.PERMISSION_GRANTED){return false;}}return true;}//如果活动或片段可以访问所有给定的权限，则返回truepublic static boolean hasSelfPermissions(Context context,String... permissions){for (String permission : permissions) {if (permissionExists(permission)&&hasSelfPermissions(context,permission)){return false;}}return true;}//如果在这个SDK版本存在的权限，则返回trueprivate static boolean permissionExists(String permission) {Integer minVersion = MIN_SDK_PERMISSIONS.get(permission);return minVersion == null || Build.VERSION.SDK_INT >= minVersion;}//确定上下文访问给定的权限。private static boolean hasSelfPermission(Context context, String permission) {try {return PermissionChecker.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED;} catch (RuntimeException t) {return false;}}//检查需要给予的权限，显示理由public static boolean shouldShowRequestPermissionRationale(Activity activity, String... permissions) {for (String permission : permissions) {if (ActivityCompat.shouldShowRequestPermissionRationale(activity, permission)) {return true;}}return false;}//获取sdk 版本@TargetApi(Build.VERSION_CODES.DONUT)public static int getTargetSdkVersion(Context context) {try {if (targetSdkVersion != -1) {return targetSdkVersion;}PackageInfo packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);targetSdkVersion = packageInfo.applicationInfo.targetSdkVersion;} catch (PackageManager.NameNotFoundException ignored) {}return targetSdkVersion;}
}

3.权限结果处理

 /*** 权限请求结果* @param requestCode* @param permissions* @param grantResults*/@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {super.onRequestPermissionsResult(requestCode, permissions, grantResults);if (mHandle==null){return;}if (PermissionUtil.shouldShowRequestPermissionRationale(this,permissions)){if (!mHandle.onNeverAsk()){Toast.makeText(this, "权限已被拒绝,请在设置-应用-权限中打开", Toast.LENGTH_SHORT).show();}}else{mHandle.onDenied();}}

4、调用

public class PermissionActivity extends XPermissionActivity implements View.OnClickListener {private Context mContext;@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_permission);mContext=PermissionActivity.this;findViewById(R.id.btn_camera).setOnClickListener(this);findViewById(R.id.btn_call).setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()){case R.id.btn_camera:requestPermission(new String[]{Manifest.permission.CAMERA}, new PermissionHandle() {@Overridepublic void onGranted() {Intent intent = new Intent(); //调用照相机intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);startActivity(intent);}@Overridepublic void onDenied() {Toast.makeText(PermissionActivity.this, "拒绝", Toast.LENGTH_SHORT).show();}});break;case R.id.btn_call:requestPermission(new String[]{Manifest.permission.CALL_PHONE}, new PermissionHandle() {@Overridepublic void onGranted() {/*Intent i=new Intent(Intent.ACTION_CALL,Uri.parse("tel:10086"));startActivity(i);*/Uri uri = Uri.parse("tel:10086");Intent intent = new Intent(Intent.ACTION_DIAL, uri);startActivity(intent);}@Overridepublic void onDenied() {Toast.makeText(PermissionActivity.this, "拒绝", Toast.LENGTH_SHORT).show();}@Overridepublic boolean onNeverAsk() {new AlertDialog.Builder(mContext).setTitle("权限申请").setMessage("在设置-应用-权限中开始电话权限，以保证功能的正常使用").setPositiveButton("去开启",new DialogInterface.OnClickListener(){@Overridepublic void onClick(DialogInterface dialog, int which) {Intent i=new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);Uri uri=Uri.fromParts("package",getPackageName(),null);i.setData(uri);startActivity(i);dialog.dismiss();}}).setNegativeButton("取消",null).setCancelable(false).show();return true;}});break;}}
}
