I have class that draws white line:

public class Line {

    //private FloatBuffer vertexBuffer;
    private FloatBuffer frameVertices;

    ByteBuffer diagIndices;


    float[] vertices = {
            -0.5f, -0.5f, 0.0f,
            -0.5f, 0.5f,  0.0f
    };

    public Line(GL10 gl) {
        // a float has 4 bytes so we allocate for each coordinate 4 bytes
        ByteBuffer vertexByteBuffer = ByteBuffer.allocateDirect(vertices.length * 4);
        vertexByteBuffer.order(ByteOrder.nativeOrder());

        // allocates the memory from the byte buffer
        frameVertices = vertexByteBuffer.asFloatBuffer();

        // fill the vertexBuffer with the vertices
        frameVertices.put(vertices);

        // set the cursor position to the beginning of the buffer
        frameVertices.position(0);

    }


    /** The draw method for the triangle with the GL context */
    public void draw(GL10 gl) {

        gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
        gl.glVertexPointer(2, GL10.GL_FLOAT, 0, frameVertices);
        gl.glColor4f(1.0f, 1.0f, 1.0f, 1f);

        gl.glDrawArrays(GL10.GL_LINE_LOOP , 0, vertices.length / 3);
        gl.glLineWidth(5.0f);

        gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
    }
}

It works fine. The problem is: When I add BG image, I don't see the line

glView = new GLSurfaceView(this);           // Allocate a GLSurfaceView

glView.setEGLConfigChooser(8, 8, 8, 8, 16, 0);
glView.setRenderer(new mainRenderer(this)); // Use a custom renderer

glView.setBackgroundResource(R.drawable.bg_day); // <- BG
glView.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
glView.getHolder().setFormat(PixelFormat.TRANSLUCENT);   

How to get rid of that?
