設置列表視圖大小Android

Question

我在我的項目中使用List View，其中我使用了一個用於創建列表項的xml文件。然后我在我的類中以編程方式使用它，由ListActivity擴展。 但問題是我必須在屏幕底部添加一個與列表視圖無關但按列表視圖覆蓋所有屏幕的按鈕。 那么，有沒有辦法在android中添加列表視圖的底部按鈕。

我的守則是： -

import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;

public class Options extends ListActivity {
    String[] items;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        requestWindowFeature(Window.FEATURE_RIGHT_ICON);

        items = getResources().getStringArray(R.array.chantOption_array);
        setListAdapter(new IconicAdapter());
        ListView lv = getListView();
        lv.setTextFilterEnabled(true);
        lv.setBackgroundResource(R.drawable.ichant_logo);
        setFeatureDrawableResource(Window.FEATURE_RIGHT_ICON, R.drawable.icon_t);


        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // When clicked, show a toast with the TextView text

                Toast.makeText(getApplicationContext(),
                        items[position], Toast.LENGTH_SHORT).show();


                if ("Gayatri Mantra".equals(items[position].toString())) {
                    int[] timeintervals = { 23900, 24000 };
                    // startChantActivity(TotalMala_loop,Total_Bead_Loop,BacgroundImage,Icon,Title,BeadsTotalTimeIntervals+totalTimeDurationOfAudio)
                    startChantActivity(2, 108, R.drawable.gayatri,
                            R.raw.gayatri, R.drawable.icon_gayatri,
                            "Gayatri Mantra", timeintervals);
                }
                if ("Om Mani Padme Hum".equals(items[position].toString())) {
                    int[] timeintervals = { 5500, 8200, 11100, 13900, 34100,
                            36700, 39500, 42300, 59300, 62000, 64800, 67600,
                            124600 };

                    // startChantActivity(TotalMala_loop,Total_Bead_Loop,BacgroundImage,Icon,Title,BeadsTotalTimeIntervals+totalTimeDurationOfAudio)

                    startChantActivity(2, 108, R.drawable.ommanipadmehum,
                            R.raw.om_mani, R.drawable.icon_padme,
                            "Om Mani Padme Hum", timeintervals);

                }
                if ("Sai Ram".equals(items[position].toString())) {

                    // Audio time interval for bead+total time duration of audio
                    int[] timeintervals = { 4800, 7500, 10400, 12600, 15800,
                            18600, 21600, 24400, 25000 };
                    // startChantActivity(TotalMala_loop,Total_Bead_Loop,BacgroundImage,Icon,Title,BeadsTotalTimeIntervals+totalTimeDurationOfAudio)
                    startChantActivity(2, 108, R.drawable.sairam, R.raw.sairam,
                            R.drawable.icon_sairam, "Sai Ram", timeintervals);
                }
                if ("Aum".equals(items[position].toString())) {
                    // Audio time interval for bead+total time duration of audio
                    int[] timeintervals = { 12850, 13000 };

                    // startChantActivity(TotalMala_loop,Total_Bead_Loop,BacgroundImage,Icon,Title,BeadsTotalTimeIntervals+totalTimeDurationOfAudio)

                    startChantActivity(2, 108, R.drawable.aum, R.raw.aum,
                            R.drawable.ico_aum, "Aum", timeintervals);
                }





            }
        });

    }



    class IconicAdapter extends ArrayAdapter {
        IconicAdapter() {
            super(Options.this, R.layout.list_item, items);

        }

        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = getLayoutInflater();
            View row = inflater.inflate(R.layout.list_item, parent, false);
            TextView label = (TextView) row.findViewById(R.id.label);
            label.setText(" "+items[position]);
            ImageView icon = (ImageView) row.findViewById(R.id.icon);
            if (items[position].equals("Gayatri Mantra")) {
                icon.setImageResource(R.drawable.icon_gayatri);
            }
            if (items[position].equals("Om Mani Padme Hum")) {
                icon.setImageResource(R.drawable.icon_padme);
            }
            if (items[position].equals("Sai Ram")) {
                icon.setImageResource(R.drawable.icon_sairam);
            }
            if (items[position].equals("Aum")) {
                icon.setImageResource(R.drawable.ico_aum);
            }
            return (row);
        }
    }


    protected void startChantActivity(int mala_loop, int beads_loop,
            int background, int media, int titleIcon, String title,
            int[] timeintervals) {

        Bundle bundle = new Bundle();
        bundle.putInt("mala_loop", mala_loop);
        bundle.putInt("beads_loop", beads_loop);
        bundle.putInt("background", background);
        bundle.putInt("media", media);
        bundle.putInt("titleIcon", titleIcon);
        bundle.putString("title", title);
        bundle.putIntArray("intervals", timeintervals);
        Intent intent = new Intent(this, ChantBliss.class);
        intent.putExtras(bundle);
        startActivityForResult(intent, this.getSelectedItemPosition());

    }
}

對應的xml文件是：

<?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="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:paddingLeft="2px"
android:paddingRight="2px"
android:paddingTop="2px"
android:layout_height="wrap_content"

/>
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="22sp"
android:textColor="#ff000000"

/>
</LinearLayout>

               android:layout_weight="1"
               android:drawSelectorOnTop="false"/>

<LinearLayout

            android:layout_weight="1"
            android:hint="Add a filter"

            />
        <Button
            android:id="@+id/addit"
            android:layout_width="wrap_content"
