Android开发之--读取文件夹下图片生成略缩图并点击显示大图
-------------
新增文件夹...
新增文件夹
(多个标签用逗号分隔)
这是一个简单的Demo，目的是：读取文件夹下图片生成略缩图并点击显示大图。
先新建一个工程，创建一个ThumbnailsWindows的类，继承LinearLayout。代码如下：
package org.winplus.thum.
import java.io.F
import java.io.FileInputS
import java.io.FileNotFoundE
import java.io.InputS
import java.util.ArrayL
import java.util.C
import java.util.I
import java.util.M
import java.util.TreeM
import android.content.C
import android.graphics.B
import android.graphics.BitmapF
import android.util.AttributeS
import android.view.LayoutI
import android.view.MotionE
import android.view.V
import android.widget.ImageB
import android.widget.ImageV
import android.widget.LinearL
import cn.embel.thum.R;
public class ThumbnailsWindows extends LinearLayout {
private static final String TAG = &ThumbnailsWindows&;
private Context mC
private static ArrayList&String& paths = new ArrayList&String&();
private ImageView imageV
public ThumbnailsWindows(Context context) {
super(context);
mContext =
setupViews();
public ThumbnailsWindows(Context context, AttributeSet attrs) {
super(context, attrs);
mContext =
setupViews();
public void setupViews() {
* 显示大图时需要使用，当然可以直接在此类中定义！这样还好控制一些~到时候再改吧，赶这过年呢
final LayoutInflater mLayoutInflater = LayoutInflater.from(getContext());
View v = mLayoutInflater.inflate(R.layout.original_photo, null);
imageView =
(ImageView) v.findViewById(R.id.original);
Map&String,Bitmap& maps = new TreeMap&String, Bitmap&();
maps = buildThum();
} catch (FileNotFoundException e) {
e.printStackTrace();
Iterator&String& it = maps.keySet().iterator();
int i = 0;
while (it.hasNext()) {
String path = (String) it.next();
Bitmap bm = maps.get(path);
ImageButton image = new ImageButton(mContext);
image.setImageBitmap(bm);
image.setId(i++);
addView(image);
image.setOnTouchListener(listener);
addView(v);
* 定义按钮控件的Touch事件
OnTouchListener listener = new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
* 控件按下的时候显示当前略缩图的大图
if(event.getAction() == MotionEvent.ACTION_DOWN){
String path = paths.get(v.getId());
InputStream inputStream =
inputStream = new FileInputStream(path);
} catch (FileNotFoundException e) {
e.printStackTrace();
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
imageView.setImageBitmap(bitmap);
* 获取图片地址列表
* @param file
private static ArrayList&String& imagePath(File file) {
ArrayList&String& list = new ArrayList&String&();
File[] files = file.listFiles();
for (File f : files) {
list.add(f.getAbsolutePath());
Collections.sort(list);
* 读取sdcard文件夹中的图片，并生成略缩图
* @throws FileNotFoundException
private Map&String,Bitmap& buildThum() throws FileNotFoundException {
File baseFile = new File(&/mnt/sdcard/tflash/image/&);
// 使用TreeMap，排序问题就不需要纠结了
Map&String,Bitmap& maps = new TreeMap&String, Bitmap&();
if (baseFile != null && baseFile.exists()) {
paths = imagePath(baseFile);
if (!paths.isEmpty()) {
for (int i = 0; i & paths.size(); i++) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = // 设置了此属性一定要记得将值设置为false
Bitmap bitmap =BitmapFactory.decodeFile(paths.get(i),options);
options.inJustDecodeBounds =
int be = options.outHeight/40;
if (be &= 0) {
options.inSampleSize =
bitmap = BitmapFactory.decodeFile(paths.get(i),options);
maps.put(paths.get(i), bitmap);
修改mail.xml文件&span style=&font-size: 16 &&&?xml version=&1.0& encoding=&utf-8&?&
&LinearLayout xmlns:android=&/apk/res/android&
android:layout_width=&fill_parent&
android:layout_height=&fill_parent&
android:orientation=&vertical& &
&org.winplus.thum.view.ThumbnailsWindows
android:layout_width=&fill_parent&
android:layout_height=&fill_parent& /&
&/LinearLayout&&/span&
本Demo还有Bug，稍后在修改吧，看能否经过修改，改成像Ihone图片浏览器一样的效果.

指点！
我估计是你用的是win7把，好像win7有问题，我以前一直在xp下可以，但是win7总报错误.回答2: [Android讨论]反编译打包出现错误
指点！
提示的是drawable下面的资源出了问题。你打包的时候是用什么打的？
