设置列表视图大小 Android

Question

我在我的项目中使用列表视图，其中使用了一个用于创建列表项的 xml 文件。然后我在我的类中以编程方式使用了它，该类由 ListActivity 扩展。 但问题是我必须在屏幕底部添加一个按钮，该按钮与列表视图无关，但列表视图覆盖了整个屏幕。 那么，有没有什么方法可以在 android 中的列表视图底部添加按钮。

我的代码是：-

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());

    }
}

相应的 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>

像这样的事情对我来说很有效：

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

<ListView android:id="@+id/list"
               android:layout_width="fill_parent" 
               android:layout_height="fill_parent"
               android:layout_weight="1"
               android:drawSelectorOnTop="false"/>

<LinearLayout
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        >
        <EditText
            android:id="@+id/newfilter"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:hint="Add a filter"

            />
        <Button
            android:id="@+id/addit"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="fill_horizontal"
            android:drawableLeft="@drawable/btn_plus_pressed"
            />
    </LinearLayout>               
</LinearLayout>
