如何制作附件活动...意味着我必须创建一个活动，其中我必须为用户建议提供编辑文本框，以及用于添加图像的图像按钮，如果有必要与他的建议相关...然后将此数据发送到服务器...

i创建了一个编辑文本并将数据发送到网络服务器..但我不知道图片上传..



我尝试过：

how to make an attachment activity... Means i have to create an activity in which i have to give a edit text box for user suggestion and an image button for adding an image if necessary related to his suggestion.. and then send this data to server...
i have created an edit text and send data to web server.. but i have no idea about image upload..

What I have tried:

public class MainActivity extends Activity implements OnClickListener {

EditText ed1;
Button submit;
Button cancel;
Button btnselectphoto; 
String toBeSent;
String imagePath=null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ed1 = (EditText) findViewById(R.id.edit1);
    submit = (Button) findViewById(R.id.submit);
    cancel = (Button) findViewById(R.id.cancel);
    submit.setOnClickListener(this);
    cancel.setOnClickListener(this);


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

@Override
public void onClick(View v) {
    if (v.getId()==R.id.submit) {
    // TODO Auto-generated method stub
    if (ed1.getText().toString().length() < 1) {

        // out of range
        Toast.makeText(this, "please enter something", Toast.LENGTH_LONG)
                .show();
    } else {
        toBeSent = ed1.getText().toString();

        new MyAsyncTask(MainActivity.this, toBeSent,imagePath).execute();
    }

}

    else if (v.getId()==R.id.cancel) {

        Toast.makeText(MainActivity.this, "thank you for comming", Toast.LENGTH_SHORT).show();
        finish();
    }
    }

private class MyAsyncTask extends AsyncTask<Void, Void, Void> {
    private Context context;
    private String data;
    private InputStream is;
    private String response;
    private String imagePath;

    public MyAsyncTask(Context context, String data,String imagePath) {
        this.context = context;
        this.data = data;
        this.imagePath=imagePath;
    }

            nameValuePairs
                    .add(new BasicNameValuePair("dataToBeSent", data));

            Toast.makeText(context, "Successfully Uploaded Comment", Toast.LENGTH_LONG).show();
            ed1.setText("");
        }
    }
