android中如何自定义ListView的高度？

我是安卓初学者。我想显示一个包含数字的自定义列表视图。我定制了我的ListView size(android:layout_height="50dp"）。但是当我运行该应用程序时，它主要显示未给出的大小。我不知道如何解决这个问题。请任何人帮助我。

活动主题列表.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.yuvi.secrectsforhappylife.TopicList">

    <ListView
        android:id="@+id/topiclist"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

标题设计.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="50dp"
    android:background="@drawable/storylist">

    <TextView
        android:id="@+id/topictitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/title"
        android:textSize="12pt"
        android:textStyle="bold"
        android:textColor="@android:color/background_light" />
</RelativeLayout>

主题列表.java

public class TopicList extends AppCompatActivity {

    String topic[]={"one","two","three","four","five","six","seven","eight","nine","ten"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_topic_list);

        ListView listView=(ListView)findViewById(R.id.topiclist);

        CustomAdapter customAdapter=new CustomAdapter();
        listView.setAdapter(customAdapter);

    }

    class CustomAdapter extends BaseAdapter
    {

        @Override
        public int getCount() {
            return topic.length;
        }

        @Override
        public Object getItem(int position) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            convertView=getLayoutInflater().inflate(R.layout.titledesign,null);
            TextView title=(TextView)convertView.findViewById(R.id.topictitle);
            title.setText(topic[position]);
            return convertView;
        }
    }
}

我想修复列表单元格高度

FYI

您想要添加HEIGHT对于每个Cell

Then

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/storylist">

    <TextView
        android:id="@+id/topictitle"
        android:layout_width="wrap_content"
        android:layout_height="50dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/title"
        android:textSize="12sp"
        android:textStyle="bold"
        android:textColor="@android:color/background_light" />

</RelativeLayout>

Note

使用 TextView 大小单位sp代替pt .
