wie man Symbolleiste zur Listenansicht hinzufügt

Question

Ich versuche, eine Symbolleiste zu einer ListView in Android Studio hinzufügen ... Ich verstehe, dass ListView Toolbar nicht unterstützt, und ich sollte appcompatactivity verwenden. Ich habe versucht, die Listview zu ändern und ich bekomme zahlreiche Fehler ... Ich habe etwa 80 verschiedene Samples angeschaut und kann nicht herausfinden, was ich überhaupt falsch mache .... wenn jemand jemals eine Toolbar und eine ListView verwendet hätte, würde ich jede zusätzliche Hilfe lieben Sie geben könnte ....

hier ist meine aktuelle Listenansicht Code

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(); 
    } 

} 

hier ist das, was ich den Code aussehen möchte, aber es funktioniert nicht

Answer 1

gefällt das (Use 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();

     @Override 
     protected void onDestroy(){ 
      super.onDestroy(); 
      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

        intent.setData(Uri.parse(getString(R.string.pro_version_url))); 
        startActivity(intent); 
        bRet=true; 
        break; 
       case R.id.action_settings_get_pro2: 
        Intent intent2 = new Intent(Intent.ACTION_VIEW); 
        intent2.setData(Uri.parse(getString(R.string.pro_version_url))); 
        startActivity(intent2); 
        bRet=true; 
        break;

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

        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); 
    } 
} 

Und in der Layout-Datei die ID des Listview

ändern

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