如何阻止文本框在Android中滚动

Question

我正在尝试创建一个带有图像和列表视图的视图，其中线性布局具有垂直方向和EditText，它应始终位于顶部。我应该可以一起滚动图像和列表视图，但不能滚动底部的EditText。

我对android很新，如果我没有任何意义，对不起。问我需要什么更多信息。

这是我的代码..

package com.example.soquestion;

import java.util.ArrayList;

import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;

import android.os.Build;

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getActionBar().hide();
        ListView listview = (ListView) findViewById(R.id.commentsListView);
        String[] values = {"January","February","March","April","May","June","July","August","September","October",
                "November","December"};
        ArrayList<String> arrayList = new ArrayList<String>();
         for (int i = 0; i < values.length; ++i) {
             arrayList.add(values[i]);
            }
         final ArrayAdapter adapter = new ArrayAdapter(this,
                    android.R.layout.simple_list_item_1, arrayList);
                listview.setAdapter(adapter);
