补充：
通过GridView仿微信动态添加本地图片
此篇文章主要讲述GridView控件实现添加本地图片并显示.主要是关于GridView控件的基本操作,通常可以通过自定义继承BaseAdapter的适配器加载图片,而下面讲述的不是自定义的适配器,而是调用SimpleAdapter实现的.至于上传发布与网络交互此处不讲述,后面文章会讲!
一. 实现效果
主要是通过点击+从本地相册中添加图片,同时显示图片至GridView.点击图片可以进行删除操作,同时界面中的发布EditView控件也很好看,不足之处在于+好没有移动至最后,但原理相同.
二. 项目工程结构
三. 界面布局详细代码
1.主界面activity_main.xml
主要通过相对布局实现,第一部分是底部的TextView,中间是EditView和GridView相对布局,下面是两个按钮.同时EditView调用res/drawable-hdpi中的editview_shape.xml,GridView显示的每张图片通过griditem_addpic.xml实现.

四. 代码详解
它主要是思想如下:
1.通过SimpleAdapter适配器实现实现加载图片,在gridView1.setOnItemClickListener()点击函数中响应不同操作.
2.当点击加号图片(+)时,调用本地相册通过Intent实现获取图片路径存于字符串pathImage.
3.获取图片路径后在onResume中刷新图片,通过GridView的setAdapter()和notifyDataSetChanged()()函数刷新加载图片.
4.点击图片时会获取其position,通过dialog()函数弹出对话框提示是否删除,通过remove实现删除.
具体代码如下所示：
-
public class MainActivity extends Activity {
-
-
private GridView gridView1;
-
private Button buttonPublish;
-
private final int IMAGE_OPEN = 1;
-
private String pathImage;
-
private Bitmap bmp;
-
private ArrayList<HashMap<String, Object>> imageItem;
-
private SimpleAdapter simpleAdapter;
-
-
@Override
-
protected void onCreate(Bundle savedInstanceState) {
-
super.onCreate(savedInstanceState);
-
setContentView(R.layout.activity_main);
-
-
-
-
-
-
getWindow().setSoftInputMode(WindowManager.LayoutParams.
-
SOFT_INPUT_ADJUST_PAN);
-
-
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
-
setContentView(R.layout.activity_main);
-
-
gridView1 = (GridView) findViewById(R.id.gridView1);
-
-
-
-
-
-
-
-
bmp = BitmapFactory.decodeResource(getResources(), R.drawable.gridview_addpic);
-
imageItem = new ArrayList<HashMap<String, Object>>();
-
HashMap<String, Object> map = new HashMap<String, Object>();
-
map.put("itemImage", bmp);
-
imageItem.add(map);
-
simpleAdapter = new SimpleAdapter(this,
-
imageItem, R.layout.griditem_addpic,
-
new String[] { "itemImage"}, new int[] { R.id.imageView1});
-
-
-
-
-
-
-
-
-
simpleAdapter.setViewBinder(new ViewBinder() {
-
@Override
-
public boolean setViewValue(View view, Object data,
-
String textRepresentation) {
-
-
if(view instanceof ImageView && data instanceof Bitmap){
-
ImageView i = (ImageView)view;
-
i.setImageBitmap((Bitmap) data);
-
return true;
-
}
-
return false;
-
}
-
});
-
gridView1.setAdapter(simpleAdapter);
-
-
-
-
-
-
gridView1.setOnItemClickListener(new OnItemClickListener() {
-
@Override
-
public void onItemClick(AdapterView<?> parent, View v, int position, long id)
-
{
-
if( imageItem.size() == 10) {
-
Toast.makeText(MainActivity.this, "图片数9张已满", Toast.LENGTH_SHORT).show();
-
}
-
else if(position == 0) {
-
Toast.makeText(MainActivity.this, "添加图片", Toast.LENGTH_SHORT).show();
-
-
Intent intent = new Intent(Intent.ACTION_PICK,
-
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
-
startActivityForResult(intent, IMAGE_OPEN);
-
-
}
-
else {
-
dialog(position);
-
-
-
}
-
}
-
});
-
}
-
-
-
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
-
super.onActivityResult(requestCode, resultCode, data);
-
-
if(resultCode==RESULT_OK && requestCode==IMAGE_OPEN) {
-
Uri uri = data.getData();
-
if (!TextUtils.isEmpty(uri.getAuthority())) {
-
-
Cursor cursor = getContentResolver().query(
-
uri,
-
new String[] { MediaStore.Images.Media.DATA },
-
null,
-
null,
-
null);
-
-
if (null == cursor) {
-
return;
-
}
-
-
cursor.moveToFirst();
-
pathImage = cursor.getString(cursor
-
.getColumnIndex(MediaStore.Images.Media.DATA));
-
}
-
}
-
}
-
-
-
@Override
-
protected void onResume() {
-
super.onResume();
-
if(!TextUtils.isEmpty(pathImage)){
-
Bitmap addbmp=BitmapFactory.decodeFile(pathImage);
-
HashMap<String, Object> map = new HashMap<String, Object>();
-
map.put("itemImage", addbmp);
-
imageItem.add(map);
-
simpleAdapter = new SimpleAdapter(this,
-
imageItem, R.layout.griditem_addpic,
-
new String[] { "itemImage"}, new int[] { R.id.imageView1});
-
simpleAdapter.setViewBinder(new ViewBinder() {
-
@Override
-
public boolean setViewValue(View view, Object data,
-
String textRepresentation) {
-
-
if(view instanceof ImageView && data instanceof Bitmap){
-
ImageView i = (ImageView)view;
-
i.setImageBitmap((Bitmap) data);
-
return true;
-
}
-
return false;
-
}
-
});
-
gridView1.setAdapter(simpleAdapter);
-
simpleAdapter.notifyDataSetChanged();
-
-
pathImage = null;
-
}
-
}
-
-
-
-
-
-
protected void dialog(final int position) {
-
AlertDialog.Builder builder = new Builder(MainActivity.this);
-
builder.setMessage("确认移除已添加图片吗？");
-
builder.setTitle("提示");
-
builder.setPositiveButton("确认", new DialogInterface.OnClickListener() {
-
@Override
-
public void onClick(DialogInterface dialog, int which) {
-
dialog.dismiss();
-
imageItem.remove(position);
-
simpleAdapter.notifyDataSetChanged();
-
}
-
});
-
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
-
@Override
-
public void onClick(DialogInterface dialog, int which) {
-
dialog.dismiss();
-
}
-
});
-
builder.create().show();
-
}
-
-
}
同时需要在AndroidMainfest.xml中添加权限操作SD卡和网络上传至服务器.
-
-
<uses-permission android:name="android.permission.INTERNET" />
-
-
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
五.
总结
该文章需要注意一个地方：在使用SimpleAdapter适配器加载bmp图片时,可能在GridView中不显示.即HashMap中map.put("itemImage",bmp)不显示图片,而使用put装入R.drawable.img却能显示.
这时有两种解决方法,一种是自定义继承BaseAdapter的适配器实现;另一种方法则是如上所示通过ViewBinder()接口实现,感谢博主dmin_提供的方法.

下面再分享个图片处理的博客。

一. 项目结构及界面
项目工程结构如下图所示:
个人还是比较欣赏这个布局的,其中MainActivity.java是主界面,ProcessActivity.java是图像处理界面,而剩余五个java对应五个不同的图像处理算法：EffectProcessImage(图像特效)、FrameProcessImage(添加相框)、IncreaseProcessImage(图像增强)、PersonProcessImage(图像交互)和WatchProcessImage(查看图片).
同时Layout中有五个xml子布局,采用PopupWindow形式显示五个不同的处理,同时该demo比较好移植,将文件依次复制过去并且MainActivity改成子活动,即可调用.
其中部分界面如下:
二. 图像查看功能
点击主界面GridView中"+"添加图片后,可以选择从相册添加或照相,加载图片进行到处理界面后,点击底部"查看"按钮它会有选中的效果(图标颜色变蓝&背景颜色加深).同时PopupWindow弹出如下界面：
三. 图像增强功能
图像增强主要是通过3个进度条SeekBar实现,可以调节图像的饱和度、亮度和色相.当饱和度等于0时就是黑白二值图像,三个滑动条可以相互调节.如下图所示：
四. 图像特效功能
PopupWindow弹出如下界面,主要包括：怀旧、浮雕、光照、素描和锐化处理.
其中特效效果和EffectProcessImage.java如下所示：
五. 图像相框添加
最后是图像相框合成,如下图所示.我采用的是照相后合成图片：
六. 总结及感想
该处理过程中的底部五个按钮切换背景和颜色详见代码ProcessActivity.Java，主要是通切换两张图片和背景实现.如果每个界面显示不同内容,建议使用Fragment滑动实现.参考：
[Android] 使用Include布局+Fragment滑动切换屏幕
[Android] 通过GridView仿微信动态添加本地图片
随手拍我还是比较满意的,其中后台数据库我们使用的是新浪SAE做的,同时ListView刷新拍拍也非常不错!效果如下：
上传的demo我把发布功能删除了,它是通过线程和Process进度条来上传多张图片的.同时ListView可以刷新最近发布消息,点击图片可以查看大图.可以对发布的拍拍进行评论、关注、点赞等操作.
但是由于整个项目是大家一起完成,包括网络、数据库(SAE)、ListView(引用开源),所以只能共享我做的那部分.抱歉~如果有时间可以写些关于Android网络方面的文章,包括如何上传图片(URL链接存储在云盘中)、获取数据库内容等操作.
PS：最近其实挺烦躁的,一方面这学期确实忙成狗了,寒假也还有个作业.但在火车上我还是挺平静的——听着调皮的钢琴曲,看着窗外流逝的繁华,不知道从什么时候自己已经喜欢上了这种26小时独处的感觉.感受颇多啊!另一个挺令我心烦的就是回家后不久就去做了个手指的小手术,今天写完这篇文章,心情稍微好点!蓦然回首,突然发现这辈子我最对不住的人居然是我自己,希望来年对自己有点,尤其是对自己的身体.同时有机会,找份实习吧!但幸运的是,每每分享一些博客、完成一些项目后都能给我带来一份快乐.
希望文章对大家有所帮助~
最后用最近看的《老人与海》结束这篇文章：
生活总是让我们遍体鳞伤,但到后来,那些受伤的地方一定会变成我们最强壮的地方.
