Android 找不到方法 requestPermissions(MainActivity,String[],int)

在申請權(quán)限時報錯
Error:(294, 27) 錯誤: 找不到符號
符號: 方法 requestPermissions(MainActivity,String[],int)
位置: 類 ActivityCompat
查過之后說可能是v4包的問題, 我嘗試修改gradle編譯版本, 也沒有作用
代碼部分:
private void checkPermissions(String[] needPermissions) {

    //獲取權(quán)限列表
    List<String> needRequestPermissonList = findDeniedPermissions(needPermissions);
    if (null != needRequestPermissonList
            && needRequestPermissonList.size() > 0) {
        //list.toarray將集合轉(zhuǎn)化為數(shù)組
        ActivityCompat.requestPermissions(this, needRequestPermissonList.toArray(new String[needRequestPermissonList.size()]),
                PERMISSON_REQUESTCODE);
    }
}

gradle的依賴部分:
dependencies {

    implementation fileTree(include: ['*.jar'], dir: 'libs')
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:26.0.0-beta1'

請問我現(xiàn)在應(yīng)該怎么做, 才能不出現(xiàn)這個問題?
