Listview解决方案

Question

我已经创建了3个编辑文本和一个按钮，我将所有3个编辑文本保存在数组列表中，并将其显示在列表中:但问题是我想

    1. first they are showing in vertically manner i want it in horizontal manner so that if i add more items it should be separated from the previous one .
    2. I want to add as many as list i want to add please provide me a hint either i should use for loop or what to get as many list as i want.        
    i was thinking to try for loop to get as many input to be added in listview.

用于java的Oncreate的主代码

公共类secondActivity扩展了AppCompatActivity {

EditText edit1,edit2,edit3;
Button button;
ListView listView;


@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.second);

    edit1=findViewById(R.id.name);
    edit2=findViewById(R.id.desigination);
    edit3=findViewById(R.id.post);

    listView = findViewById(R.id.list_view);


    button = findViewById(R.id.list_button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ArrayList<String> arryList = new ArrayList<String>();
            arryList.add(edit1.getText().toString());
            arryList.add(edit2.getText().toString());
            arryList.add(edit3.getText().toString());

            ArrayAdapter list = new ArrayAdapter(secondActivity.this,android.R.layout.simple_list_item_1,arryList);
            listView.setAdapter(list);
            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                    Toast.makeText(secondActivity.this, "hello "+ position, LENGTH_SHORT).show();
                }
            });
        }
    });

}

没有错误开始只是它在垂直我的列表播种，我想它在同一行中，并希望添加尽可能多的项目在列表中的同时它不工作，只有我能够添加它为一次

Answer 1

可以使用HorizontalListView属性或将orientation属性添加到ListView或RecyclerView，而不是ArrayList。

Answer 2

您可以使用此代码模型随时将项目添加到列表视图中：

public class MyListView extends ListActivity {

ArrayList<String> listItems = new ArrayList<String>();
ArrayAdapter<String> adapter;

int myCounter = 0;

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);
    adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1,
        listItems);
    setListAdapter(adapter);
}

//METHOD WHICH WILL HANDLE DYNAMIC INSERTION
public void addItemsToList(View v) {
    listItems.add("Clicked : " + MyCounter++);
    adapter.notifyDataSetChanged();
}

}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
    <Button
        android:id="@+id/addBtn"
        android:text="Add New Item"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="addItemsToList"/>
    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"
    />
</LinearLayout>

您还可以使用HorizontalListView将项目水平添加到列表中
