android上传文件

1.Android端：

1.1 布局文件：

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

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    
     <TextView
        android:id="@+id/mTextView1" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />

      <TextView
        android:id="@+id/mTextView2" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
      
        <Button
        android:id="@+id/mButton1" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
     
</LinearLayout>

1.2 Activity：

package org.yang.android.upload;

		mTextView1.setText("FilePath：/n" + uploadFile);
		mTextView2 = (TextView) findViewById(R.id.mTextView2);
		mTextView2.setText("UploadPath：/n" + actionUrl);
		/* 设定mButton的onClick事件处理 */
		mButton1 = (Button) findViewById(R.id.mButton1);
		mButton1.setOnClickListener(new View.OnClickListener()
		{
			public void onClick(View v)
			{
				FileUplaodUtil.uploadFile(AndroidUploadFileActivity.this.file, actionUrl);
			}
		});
	}
}

2.服务器端：

	}
