错误：包android.support.v7.internel.widget不存在

Question

我开发了一个Android应用程序（API 23），但它不起作用。我发现了这个错误：

  E:\AllInOne1\app\src\main\java\eniso\ia32\Rabie\allinone\spinnerActivity.java
  Error:(3, 42)

build.gradle（app）

apply plugin: 'com.android.application'

android {
compileSdkVersion 'Google Inc.:Google APIs:23'
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "eniso.ia32.Rabie.allinone"
    minSdkVersion 11
    targetSdkVersion 21
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_5
        targetCompatibility JavaVersion.VERSION_1_5
    }
  }

  buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.txt'
    }
   }
   }

   dependencies {
   compile 'com.android.support:appcompat-v7:23.1.1'
   compile 'com.android.support:appcompat-v7:23.1.1'

    }

我已安装＆＃34; android支持库＆＃34;但它不起作用

snipperActivity.java ：

 package eniso.ia32.Rabie.allinone;

import android.support.v7.internal.widget.AdapterViewCompat;
import   android.support.v7.internal.widget.AdapterViewCompat.OnItemSelectedListener;
import android.view.View;
import android.widget.AdapterView;

public class spinnerActivity extends TourismActivity implements OnItemSelectedListener {

 public void onItemSelected(AdapterView<?> parent, View view, 
            int pos, long id) {
        // An item was selected. You can retrieve the selected item using
        // parent.getItemAtPosition(pos)
    }

    public void onNothingSelected(AdapterView<?> parent) {
        // Another interface callback
    }



    @Override
    public void onItemSelected(AdapterViewCompat<?> arg0, View arg1,
            int arg2, long arg3) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onNothingSelected(AdapterViewCompat<?> arg0) {
        // TODO Auto-generated method stub

    }

  }
