android - ListView setOnItemClickListener 不工作

Question

我有一个项目 ListView ，每个项目都有一些 ImageView 和 TextView 。我在谷歌上搜索了很多解决方案，但没有一个对我有帮助。我是 android 开发的新手，我想我失去了一些明显的东西。我还假设也许我尝试了太多的解决方案，并且它们以某种方式相互阻塞。请帮帮我。 这是我的代码:

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;
    }

每次点击真正记录的唯一内容是:

这是我的主要布局 xml 文件:

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

android:layout_height="fill_parent"
android:background="@drawable/bg_clear"

android:paddingBottom="10dp">

Answer 1

试试这个

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);

}
});

或

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) {

        }
    });

替代方法

@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;
    }
