I'm trying to create a customized clock that given certain input will
highlight a certain section of the clock (e.g. draw pie shapes
highlights on top of the clock).
Here's my problem:
I'm trying to use drawArc in the Canvas class. I am able to draw 360
degree arcs, but nothing shows up when I draw any arcs less than 360
degree. I'd like to draw around 15 degree arcs, but when I put 15 into
the sweep angle location, nothing gets drawn. It only draws full
circles (360). Does anyone know what's wrong? Below is my code.
ACTIVITY CLASS:
import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class AdherenceClock extends Activity {
private ClockView clockView = null;
public Document xml = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.clockView = new ClockView(this);
//Remove the title bar, set to full screen, and set to
landscrape
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags
(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setRequestedOrientation
(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setContentView(this.clockView);
}
}
CLOCKVIEW CLASS:
package nmm.android.adherenceclock;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.RectF;
import android.view.View;
public class ClockView extends View {
protected final Paint pmColor = new Paint();
protected final Paint amColor = new Paint();
public ClockView(Context context) {
super(context);
this.setBackgroundDrawable(getResources().getDrawable
(R.drawable.clockbackground));
this.amColor.setARGB(100, 248, 225, 110);
this.pmColor.setARGB(100, 111, 162, 214);
}
@Override
protected void onDraw(Canvas canvas) {
RectF clockRect = new RectF(86, 314, 394, 6);
canvas.drawArc(clockRect, 0, 20, true, this.amColor);
}
}
This doesn't work. It only works for 360 degrees. What's wrong?
