android 实现一个简单纯文本的ListView

思维线路：

1.创建一个ListViewActivity， LinearLayout 布局里写了一个ListView布局

2.创建一个TextView布局给ArrayAdapter适配器使用

3.将TextView布局和数据导入适配器ArrayAdapter

3.将ArrayAdapter适配好的内容导入ListView布局

代码如下：

ListViewActivity 的布局：

<?xml version="1.0" encoding="utf-8"?>

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

    android:layout_width="match_parent"

    android:layout_height="match_parent">

    <ListView

        android:id="@+id/SimpleListView"

        android:layout_width="match_parent"

        android:layout_height="match_parent"></ListView>

</LinearLayout>

TextView 的布局：

<?xml version="1.0" encoding="utf-8"?>

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

    android:id="@+id/ListTextView"

    android:orientation="vertical"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:padding="10dp"

    android:layout_marginLeft="20dp"

    android:text="内容"

    android:textSize="50dp">

</TextView>

onCreate实现代码：

package com.example.prize.mylistviewdemoapp;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.widget.ArrayAdapter;

import android.widget.ListView;

public class SimpleListView extends AppCompatActivity {

    private String [] data ={"苹果","橘子","芒果","香蕉","柠檬","火龙果","西瓜","李子",

            "芭乐","石榴","葡萄","荔枝","圣女果","杨梅","柿子","山竹","杨桃","雪梨","猕猴桃","榴莲"

            ,"枇杷","樱桃","柚子","水蜜桃","桑葚","莲雾"};

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_simple_list_view);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(SimpleListView.this,R.layout.list_layout,data);//适配器

        ListView listView = (ListView) findViewById(R.id.SimpleListView); //找到ListView布局

        listView.setAdapter(adapter); //导入

    }

}
