I have created my ownView (extend class View) and override function
onDraw() in it
I wanted to use it in my xml file design :D
but when i put it inside the file an error happens when the program
runs so if anyone can help me to do so as i make whole imnterface
using xml and i wanna add this new class in between.
The code:
This is the new view:
package com.android.mobi3.player;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.RectF;
import android.graphics.Paint.Style;
import android.view.View;
/**
*
* @author Ahmed Abdel Samea
* This Class is used to provide a view to user to draw
* the seek bar.
*
*/
public class SeekTimer extends View {
/
*---------------------------------------------------------------------------
*/
/
*---------------------------------------------------------------------------
*/
/
*---------------------------------------------------------------------------
*/
/* Variables Area
/
*---------------------------------------------------------------------------
*/
/
*---------------------------------------------------------------------------
*/
/
*---------------------------------------------------------------------------
*/
//width of the drawing
protected final int ARCSTROKEWIDTH = 20;
//values
protected int mySecondsPassed = 0;
protected int mySecondsTotal = 0;
//used to draw the timer by no. and seek bar
protected final Paint myArcSecondPaint = new Paint();
protected final Paint myArcMinutePaint = new Paint();
protected final Paint myCountDownTextPaint = new Paint();
/
*---------------------------------------------------------------------------

/

*/
/* Constructor

*/
public SeekTimer(Context context) {
super(context);
/******************************************************/
/**---- Setting the timer and seek bar drawer ----*/
/******************************************************/
// Black text for the countdown
this.myCountDownTextPaint.setARGB(150, 0, 0, 0);
this.myCountDownTextPaint.setTextSize(110);
this.myCountDownTextPaint.setFakeBoldText(true);
// Our arc fill be a lookthrough-red.
this.myArcMinutePaint.setARGB(150, 170, 0, 0);
this.myArcMinutePaint.setAntiAlias(true);
this.myArcMinutePaint.setStyle(Style.STROKE);
this.myArcMinutePaint.setStrokeWidth(ARCSTROKEWIDTH);
this.myArcSecondPaint.setARGB(200, 255, 130, 20);
this.myArcSecondPaint.setAntiAlias(true);
this.myArcSecondPaint.setStyle(Style.STROKE);
this.myArcSecondPaint.setStrokeWidth(ARCSTROKEWIDTH / 3);
}
// ===========================================================
// Getter & Setter
// ===========================================================
public void updateSecondsPassed(int someSeconds){
this.mySecondsPassed = someSeconds;
}
public void updateSecondsTotal(int totalSeconds){
this.mySecondsTotal = totalSeconds;
}
public int getSecondsPassed(){
return mySecondsPassed;
}
@Override
protected void onDraw(Canvas canvas) {
/* Calculate the time left,
* until our pizza is finished. */
int secondsLeft = this.mySecondsTotal - this.mySecondsPassed;
if(secondsLeft>0){
// At least one second left
float angleAmountMinutes = ((this.mySecondsPassed *
1.0f)
/
this.mySecondsTotal)
* 360;
float angleAmountSeconds = ((60 -secondsLeft % 60) *
1.0f)
/ 60
* 360;
/* Calculate an Rectangle,
* with some spacing to the edges */
RectF arcRect = new RectF(ARCSTROKEWIDTH / 2,
ARCSTROKEWIDTH / 2,
this.getWidth() -
ARCSTROKEWIDTH / 2,
this.getHeight() -
ARCSTROKEWIDTH / 2);
// Draw the Minutes-Arc into that rectangle
canvas.drawArc(arcRect, -90, angleAmountMinutes,
this.myArcMinutePaint);
// Draw the Seconds-Arc into that rectangle
canvas.drawArc(arcRect, -90, angleAmountSeconds,
this.myArcSecondPaint);
}
}
}
code and I wrote in the xml:(I write it in relative layout)
Line 23: <SeekTimer android:id="@+id/seek_bar"
android:layout_width="50px"
android:layout_height="50px"
android:layout_centerHorizontal="true"/>
The error that i get:
ComponentInfo{com.android.mobi3.player/
com.android.mobi3.player.PlayerGUI}
android.view.ViewInflate$Inflate Exception: Binary XML file line
#23:Error inflating class SeekTimer.
