Question

我有一个listView插入到一个对话框中，当我点击列表中的项目时它没有响应动作，我已经设置了听众，但我不明白为什么{{1}没有被调用。

onItemClickListener

list_item_to_meet.xml

   public void init() {
        toMeetDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        toMeetDialog.setContentView(R.layout.person_to_meet);
        listOfPersonToFollow = (ListView) toMeetDialog.findViewById(R.id.list_view_to_meet);
        confirmButton = (Button) toMeetDialog.findViewById(R.id.button_to_meet);
        confirmButton.setOnClickListener(this);
        listOfPersonToFollow.setOnItemClickListener(this);
        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(mapsActivity, R.layout.list_item_to_meet, mapsActivity.getPersonToFollow());
        listOfPersonToFollow.setAdapter(arrayAdapter);
        toMeetDialog.show();

    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Toast.makeText(mapsActivity, "hello", Toast.LENGTH_SHORT);
    }

person_to_meet.xml

    <?xml version="1.0" encoding="utf-8"?>
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/item"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:textSize="26dp" />

这段代码有什么问题？提前谢谢。

我遇到过在列表行中设置按钮的OnClickListener使得'blockDescendants'徒劳无功的情况。设置OnClickListener后，使该按钮无法通过setFocusable(false)和setFocusableInTouchMode(false)关注。

试试这个：

public void init() {
        toMeetDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        toMeetDialog.setContentView(R.layout.person_to_meet);
        listOfPersonToFollow = (ListView) toMeetDialog.findViewById(R.id.list_view_to_meet);
        confirmButton = (Button) toMeetDialog.findViewById(R.id.button_to_meet);
        confirmButton.setOnClickListener(this);
        confirmButton.setFocusable(false);
        confirmButton.setFocusableInTouchMode(false);
        listOfPersonToFollow.setOnItemClickListener(this);
        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(mapsActivity, R.layout.list_item_to_meet, mapsActivity.getPersonToFollow());
        listOfPersonToFollow.setAdapter(arrayAdapter);
        toMeetDialog.show();
    }

listView项目不响应click
