ImageLoader在Gridview中的使用

Posted 2020-09-30 luzhouxiaoshuai

原理和ImageLoader在Listview中的使用一样，只有下面的几点变化

主页面的布局

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

    <TextView
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:background="@android:color/holo_blue_light"
        android:gravity="center"
        android:text="ImagleLoager_Gridview"
        android:textColor="@android:color/white"
        android:textSize="25sp" />

    <GridView
        android:id="@+id/gv_imageloader"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:horizontalSpacing="4dip"
        android:numColumns="3"
        android:padding="4dip"
        android:stretchMode="columnWidth"
        android:verticalSpacing="4dip" />

</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:orientation="horizontal">
    <ImageView
        android:src="@drawable/ic_launcher"
        android:id="@+id/image"
        android:layout_width="50dp"
        android:layout_height="50dp" />
    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/holo_blue_light"
        android:gravity="center"
        android:text="ImagleLoager_Listview"
        android:textColor="@android:color/white"
        android:textSize="25sp" />


</LinearLayout>

主页面发生改变：其他都不会有变化：

package application.weiyuan.com.listviewimageloader;

import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.GridView;
import android.widget.ListView;

public class MainActivity extends Activity {

    private GridView gridView;
    private ListViewAdapter listViewAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        initData();
    }

    private void initView() {
        gridView = (GridView)findViewById(R.id.gv_imageloader);
    }

    private void initData() {
// 创建适配器
        listViewAdapter = new ListViewAdapter(MainActivity.this);
// 添加适配器到listview中
        gridView.setAdapter(listViewAdapter);
    }

}
