android:id="@+id/ctrlandinfo" android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:padding="5px">

android:layout_width="wrap_content" android:layout_height="wrap_content"
android:src="@drawable/icon" />
<ImageButton android:id="@+id/stop" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:src="@drawable/icon" />
<LinearLayout android:id="@+id/trackinfo"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/tracktitle" android:layout_width="fill_parent"
android:text="track name" android:textSize="25px" android:textColor="#ffffff"
android:ellipsize="marquee" android:marqueeRepeatLimit="marquee_forever"
android:singleLine="true" android:focusable="true" />
<LinearLayout android:id="@+id/otherinfo"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content">

android:layout_height="wrap_content" android:layout_weight="1"
android:text="artists" />
<TextView android:id="@+id/tracktitle" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1"
android:text="albums" />
</LinearLayout>
</LinearLayout>
</LinearLayout>在TinyPlayer.java里面是package com.payne.android.TinyPlayer;import android.app.Activity;
import android.os.Bundle;public class TinyPlayerActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

Answer 1
