ListView打开新活动

大家好我的问题是如何使用ListView在新活动中显示水平图像。但是，当我点击列表项目的“ONE”时，它可能会回到主菜单，我已经搜索了同样的问题但它不起作用。我该怎么办？这是我的MainMenu类

public class MainMenu extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_menu);
}
public void Click(View view){
    Intent fors = new Intent(this, ListViewOfMunicipalities.class);
    startActivity(fors);
}

MainMenu xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainMenu">



<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="ALBAY MABUHAY"
    android:id="@+id/button"
    android:onClick="Click"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="52dp"
    android:background="#51010101"
    android:textColor="#ffffff" />

它将转到ListViewOfMunicipalties

public class ListViewOfMunicipalities extends AppCompatActivity {



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_list_view_of_municipalities);

    String[] Municipalities = {" Tiwimunicipalitity", "TabacoMunicipality", "MalinaoMunicipality"};

    ListAdapter forsAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,Municipalities);
    ListView mlistView = (ListView) findViewById(R.id.mlistView);
    mlistView.setAdapter(forsAdapter);

    mlistView.setOnItemClickListener(
            new AdapterView.OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {


                    switch( position ) {
                        case 0:  Intent TiwiActivity;
                            TiwiActivity = new Intent(ListViewOfMunicipalities.this, TiwiMunicipality.class);
                            startActivity(TiwiActivity);
                            break;
                        case 1:  Intent TabacoActivity = new Intent(ListViewOfMunicipalities.this,  TabacoMunicipality.class);
                            startActivity(TabacoActivity);
                            break;
                            default:

                    }

                }
            }
    );

}

当我点击案例0时，它将转到TiwiMunicipality.class，当我点击案例1这是TabacoMunicipality.class时，它可能会回到主菜单，这就是错误:(。这是TiwiMunicipality的代码的.class

public class TiwiMunicipality extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tiwi_municipality);
    Intent TiwiActivity=new Intent();
    setResult(RESULT_OK, TiwiActivity);
    //finish();
}

TiwiMunicipality的xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

   <HorizontalScrollView

       android:layout_height="250dp">

       <LinearLayout

           <ImageView
               android:layout_width="300dp"
               android:layout_height="250dp"
               android:id="@+id/img"
               android:background="@mipmap/a" />

           <ImageView
               android:layout_width="300dp"
               android:layout_height="250dp"

               android:background="@drawable/ganda" />

       </LinearLayout>

   </HorizontalScrollView>

</LinearLayout>

这是TabacoMunicipality.class

public class TabacoMunicipality extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tabaco_municipality);
    Intent TabacoActivity=new Intent();

    //finish();
