Listview setOnItemClickListener funktioniert nicht

Question

Ich habe eine Liste von Elementen, jedes Element hat einige Bilder und Textansichten. Ich habe viele Lösungen gegooglet, aber keine von ihnen hat mir geholfen. Ich bin sehr neu in Android-Entwicklung, ich denke, ich verliere etwas offensichtlich. Ich nehme auch an, dass ich vielleicht zu viele Lösungen ausprobiert habe und sie sich irgendwie blockieren. Bitte hilf mir. hier ist mein Code:

public class MyActivity extends Activity { 
private List<Lesson> lessons = new ArrayList<Lesson>(); 

private int loop_count = 0; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.my_layout); 

    FillLessonList(); 
    FillListView(); 
} 
    private void FillListView() 
{ 
    ArrayAdapter<Lesson> adapter = new MyListAdapter(); 
    ListView list = (ListView) findViewById(R.id.lessonsList); 
    list.setAdapter(adapter); 

    list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
           int position, long id) { 
      Log.i("debug", "item click: " + view.findViewById(R.id.lesson_text_lesson_name)); 

      Toast.makeText(getApplicationContext(), "Your toast message.", 
        Toast.LENGTH_SHORT).show(); 

      Intent intent = new Intent(view.getContext(), LessonActivity.class); 
      startActivity(intent); 
     } 
    }); 
} 

private class MyListAdapter extends ArrayAdapter<Lesson> 
{ 
    MyListAdapter() 
    { 
     super(MyActivity.this, R.layout.lesson_item, lessons); 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View lessonView = convertView; 
     if(lessonView == null) 
     { 
      lessonView = getLayoutInflater().inflate(R.layout.lesson_item, parent, false); 
     } 

     Lesson currentLesson = lessons.get(position); 

     //here I add all the needed info into the item. 
     //This part works fine and displays everything I need properly. 

     return lessonView; 
    } 

Das einzige, was wirklich mit jedem Klick wird protokolliert ist:

Hier ist meine Haupt-Layout XML-Datei:

Answer 1

versuchen, diese

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

Log.i("debug", "item click: " + view.findViewById(R.id.lesson_text_lesson_name)); 

      Toast.makeText(getApplicationContext(), "Your toast message.", 
        Toast.LENGTH_SHORT).show(); 

      Intent intent = new Intent(view.getContext(), LessonActivity.class); 
      startActivity(intent); 

} 
}); 

oder

list.setOnItemClickListener(new AdapterView.OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
      Log.i("debug", "item click: " + view.findViewById(R.id.lesson_text_lesson_name)); 

     Toast.makeText(getApplicationContext(), "Your toast message.", 
       Toast.LENGTH_SHORT).show(); 

     Intent intent = new Intent(view.getContext(), LessonActivity.class); 
     startActivity(intent); 

     } 

     @Override 
     public void onNothingSelected(AdapterView<?> parent) { 

     } 
    }); 

Alternative Methode

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View lessonView = convertView; 
     if(lessonView == null) 
     { 
      lessonView = getLayoutInflater().inflate(R.layout.lesson_item, parent, false); 
     } 

     Lesson currentLesson = lessons.get(position); 

     //here I add all the needed info into the item. 
     //This part works fine and displays everything I need properly. 

     lessonView.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Log.e(""testing123,"testing"); 
      Toast.makeText(MyActivity.this, "Your toast message.", 
       Toast.LENGTH_SHORT).show(); 

     Intent intent = new Intent(MyActivity.this, LessonActivity.class); 
     startActivity(intent); 
     } 
    }); 

     return lessonView; 
    } 

Answer 2

Da Sie einen benutzerdefinierten Adapter haben, müssen Sie die OnClickListener haben in Seite von getView(). Also, wenn Sie etwas Aktion möchten, wenn der Benutzer das ImageView-lection_icon sagt, dann möchten Sie vielleicht etwas wie schreiben:

lessonView.findViewById(R.id.lesson_icon).setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Toast.makeText(MainActivity.this, "Image clicked", Toast.LENGTH_SHORT).show(); 
      } 
     });
