很简单的UI。点击按钮然后从图片库中选择图片上传（非主线程）。
andriod 主LoadActivity的代码如下：
public class LoadActivity extends Activity {
public static final String TAG_STRING="LoadActivity";
private String pathString=null;
static final int flag_load=4;
private Button button=null;
private userUploadService service=new userUploadServiceImpl();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_load);
button=(Button) this.findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String status = Environment
.getExternalStorageState();
if (status.equals(Environment.MEDIA_MOUNTED)) {// 判断是否有SD卡
Intent intent=new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, flag_load);
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.load, menu);
return true;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==flag_load)
{
if(data==null)
{
Toast.makeText(this, "你没有选择任何图片", Toast.LENGTH_LONG).show();
}
else
{
Uri uri=data.getData();
if (uri==null) {
Toast.makeText(this, "你没有选择任何图片", Toast.LENGTH_LONG).show();
}
else {
String path=null;
String[] pojoStrings={MediaStore.Images.Media.DATA};
Cursor cursor=getContentResolver().query(uri, pojoStrings, null, null, null);
if(cursor!=null)
{
int col=cursor.getColumnIndexOrThrow(pojoStrings[0]);
cursor.moveToFirst();
path=cursor.getString(col);
cursor.close();
}
if(path==null)
{
Toast.makeText(this, "未获得图片路径", Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(this, "图片路径为"+path, Toast.LENGTH_LONG).show();
pathString=path;
new AlertDialog.Builder(this)
.setTitle("提示")
.setMessage("你要选择这张图片上传么？")
.setPositiveButton("确定",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
doUpload();
}
} ).create().show();
}
}
}
}
}
private void doUpload() {
new Thread(new Runnable() {
@Override
public void run() {
try {
InputStream in=new FileInputStream(new File(pathString));
Map<String, String>data=new HashMap<String, String>();
data.put("Name", "liuming");
data.put("Gender", "男");
final String retString=service.userUpload(in, data,pathString);
Log.d(TAG_STRING, retString);
} catch (Exception e) {
e.printStackTrace();
// runOnUiThread(new Runnable() {
// public void run() {
// Toast.makeText(LoadActivity.this, "上传更新出错", Toast.LENGTH_LONG).show();
// }
// });
}
}
}).start();
}
}
<span style="font-family: Arial, Helvetica, sans-serif;">service.userUpload(in, data,pathString)</span>
为处理上传逻辑的接口类实现。
