如何将工具栏添加到列表视图

Question

我正在尝试将工具栏添加到Android Studio中的列表视图...我知道ListView不支持工具栏，我应该使用AppcompatActivity。我试图更改列表视图，但出现许多错误...我看了大约 80 个不同的样本，根本无法弄清楚我做错了什么......如果有人曾经使用过工具栏和列表视图，我希望你能提供任何额外的帮助......

这是我当前的列表视图代码

package mypackage.android;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.View;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import mypackage.android.database.CommonNamesAdapter;
public class CommonNames extends ListActivity {
    CommonNamesAdapter cnTable;
    ListView cnListView;
    Cursor c;
    private static final int COMMON_NAME_ACTIVITY_START = 1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.common_names_list);
        cnTable = new CommonNamesAdapter();
        cnTable.open(getApplicationContext());
        c = cnTable.fetchAllCommonNames();
        startManagingCursor(c);
        if(c!=null){
            SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
                    R.layout.common_names_row,
                    c,
                    new String[] {c.getColumnName(1)},
                    new int[] {R.id.commonName});
            setListAdapter(adapter);
        }
    }
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        c.moveToPosition(position);
        Intent i = new Intent(this, CommonNameDescription.class);
        i.putExtra(CommonNamesAdapter.COMMON_NAME_ROWID, id);
        i.putExtra(CommonNamesAdapter.COMMON_NAME, c.getString(
                c.getColumnIndexOrThrow(CommonNamesAdapter.COMMON_NAME)));
        i.putExtra(CommonNamesAdapter.COMMON_NAME_COUNT, c.getString(
                c.getColumnIndexOrThrow(CommonNamesAdapter.COMMON_NAME_COUNT)));
        startActivityForResult(i, COMMON_NAME_ACTIVITY_START);
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        //Bundle extras = intent.getExtras();
        switch(requestCode) {
        default: break;
        }
    }
    @Override
    protected void onDestroy(){
        super.onDestroy();
        c.close();
        cnTable.close();
    }
}

这是我希望代码的样子，但它不起作用

像这样做(使用 AppCompatActivity(

public class CommonNames extends AppCompatActivity implements AdapterView.OnItemClickListener {
        CommonNamesAdapter cnTable;
        ListView cnListView;
        Cursor c;
        private static final int COMMON_NAME_ACTIVITY_START = 1;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.common_names_list);
            Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
            setSupportActionBar(toolbar);
            cnListView= (ListView) findViewById(R.id.cnListView);
            cnTable = new CommonNamesAdapter();
            cnTable.open(getApplicationContext());
            c = cnTable.fetchAllCommonNames();
            startManagingCursor(c);
            if(c!=null){
                SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
                        R.layout.common_names_row,
                        c,
                        new String[] {c.getColumnName(1)},
                        new int[] {R.id.commonName});
                cnListView.setAdapter(adapter);
                cnListView.setOnItemClickListener(this);
            }
        }
        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
            super.onActivityResult(requestCode, resultCode, intent);
            //Bundle extras = intent.getExtras();
            switch(requestCode) {

            }

            c.close();
            cnTable.close();
        }
        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.menu_main, menu);
            return true;
        }

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            boolean bRet=false;//set true is menu selection handled
            switch (item.getItemId()) {

                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse(getString(R.string.pro_version_url)));

                    intent3.setData(Uri.parse(getString(R.string.rate_this_app_url)));
                    startActivity(intent3);
                    bRet=true;
                    break;
                case R.id.action_settings_privacy_policy:

                    intentprivacy.setData(Uri.parse(getString(R.string.privacy_policy_url)));
                    startActivity(intentprivacy);
                    bRet=true;
                    break;
                case R.id.action_settings_all_our_apps:
                    Intent intent4 = new Intent(Intent.ACTION_VIEW);
                    intent4.setData(Uri.parse(getString(R.string.all_our_apps_url)));
                    startActivity(intent4);
                    bRet=true;
                    break;
                default:
                    bRet=super.onOptionsItemSelected(item);
            }
            return bRet;
        }

    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
        c.moveToPosition(position);
        Intent i = new Intent(this, CommonNameDescription.class);
        i.putExtra(CommonNamesAdapter.COMMON_NAME_ROWID, id);
        i.putExtra(CommonNamesAdapter.COMMON_NAME, c.getString(
                c.getColumnIndexOrThrow(CommonNamesAdapter.COMMON_NAME)));
        i.putExtra(CommonNamesAdapter.COMMON_NAME_COUNT, c.getString(
                c.getColumnIndexOrThrow(CommonNamesAdapter.COMMON_NAME_COUNT)));
        startActivityForResult(i, COMMON_NAME_ACTIVITY_START);
    }
}

并在布局文件中更改列表视图的id

<ListView 
android:id="@+id/cmListView"
android:height="" ....../>
