Question

I’m starting to work on a game, which will have 3 views stacked on top of each other, basically a logo/ad row, a score row, and a game row. To start out with, I’m trying to have a class called Level_Score_Bar that uses an XML layout called score_bar_layout. Right now, my main XML code looks like this (Note, I’ve been editing this based off of the suggestions below, if I get it fixed, I’ll stop editing it):

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_height="fill_parent" android:layout_width="fill_parent">
    <LinearLayout android:layout_height="wrap_content" android:orientation="horizontal" android:layout_width="fill_parent" android:id="@+id/Title_bar">
        <ImageView android:layout_height="wrap_content" android:id="@+id/imageView1" android:layout_width="wrap_content" android:src="@drawable/icon"></ImageView>
        <LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/linearLayout4">
        </LinearLayout>
    </LinearLayout>
    <pearsonartphoto.AJEG.Level_Score_bar android:layout_height="fill_parent" android:layout_width="wrap_content" android:id="@+id/Score_Bar">
    </pearsonartphoto.AJEG.Level_Score_bar>
    <LinearLayout android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="vertical" android:id="@+id/Game_Row">
        <View android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/view3"></View>
    </LinearLayout>
</LinearLayout>

Level_Score_bar.java looks like this:

public class Level_Score_bar extends RelativeLayout {
public Level_Score_bar(Context context, AttributeSet set, int defStyle) {
    this(context,set);
}

public Level_Score_bar(Context context, AttributeSet set) {
    super(context, set);
    this.addView(View.inflate(context,R.layout.score_bar_layout,null));
    Log.d(TAG,"Added view");
}
}

score_bar_layout.xml looks like this

<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent" android:layout_height="wrap_content">
    <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="@string/level" android:id="@+id/Level_text" android:layout_toRightOf="@+id/Level_text"></TextView>
    <TextView android:id="@+id/Current_Level" android:layout_width="wrap_content" android:text="TextView" android:layout_height="wrap_content" android:layout_alignParentTop="true"></TextView>
    <TextView android:layout_width="wrap_content" android:text="TextView" android:layout_height="wrap_content" android:layout_centerVertical="false" android:layout_centerHorizontal="true" android:id="@+id/Time_Left"></TextView>
    <TextView android:id="@+id/Score_Label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentRight="true" android:text="@string/score"></TextView>
    <TextView android:layout_width="wrap_content" android:text="TextView" android:layout_height="wrap_content" android:layout_toRightOf="@+id/Score_Label" android:id="@+id/Score_Value"></TextView>
</RelativeLayout>

The problem is, I’m not seeing the view at all. I’m sure I’m missing something small, but I can’t for the life of me figure it out. I’ve confirmed that the addView command is being called (Via a Log.d statement), but it’s just not seeming to make any difference…

You’re using the wrong constructor if I remember correctly, try this one instead:

public Level_Score_bar(Context context, AttributeSet set, int defStyle) {
    super(context, set, defStyle);
    // ... 
}

[Edit]
Forgot to mention that since you’re creating the view from XML, Android will call this constructor and it also enables you to use custom attributes if you so wish.
