1.專案的git地址

https://github.com/lantian0314/StudioTest.git

2.首先配置app中的build.gradle以及manifest

 compile 'com.tbruyelle.rxpermissions:rxpermissions:[email protected]'
 compile 'io.reactivex:rxandroid:1.0.1'
 compile 'io.reactivex:rxjava:1.0.14'

manifest許可權配置

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.CAMERA"></uses-permission>

3.下面的程式碼是申請動態許可權功能

private void requestRxPermission(String... permissions) {
        RxPermissions rxPermissions = new RxPermissions(this);
        rxPermissions.request(permissions).subscribe(new Observer<Boolean>() {
            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable e) {

            }

            @Override
            public void onNext(Boolean result) {
                if (result) {
                    Toast.makeText(RxPermission.this, "同意權限", Toast.LENGTH_LONG).show();
                } else {
                    Toast.makeText(RxPermission.this, "拒絕許可權", Toast.LENGTH_LONG).show();
                }
            }
        });
    }
 

public  static  String checkPermission(Context context,String ... permissions){
        StringBuilder builder=new StringBuilder();
        try {
            for (String permission:permissions
                 ) {
                builder.append(permission);
                builder.append(" is apply state : ");
                builder.append(checkPermissionState(context,permission));
                builder.append("\n\n");
            }
            return  builder.toString();
        }catch (Exception e){

        }finally {
            if (builder!=null){
                builder.delete(0,builder.length());
            }
        }
        return "";
    }

    private  static  boolean checkPermissionState(Context context,String permission){
        if (context==null|| TextUtils.isEmpty(permission)) {
            return false;
        }
        try {
            if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.M) {
                int tragetVersion = context.getPackageManager().getApplicationInfo(context.getPackageName(), PackageManager.GET_META_DATA).targetSdkVersion;
                if (tragetVersion >= Build.VERSION_CODES.M) {
                    return context.checkSelfPermission(permission) == PackageManager.PERMISSION_GRANTED;
                } else {
                    return PermissionChecker.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED;
                }
            }
        }catch (Exception e){
        }
        return  false;
    }
