Customizing the horizontal progress bar

That is true:

Next, paste the code for everyone:

The first is the custom ProgressBar:

public class Myprogress extends ProgressBar {

String text;

Paint Mpaint;

Public myprogress (Context context) {

Super (context);

TODO auto-generated Constructor stub

System.out.println ("1");

Inittext ();

}

Public myprogress (context context, AttributeSet attrs, int defstyle) {

Super (context, attrs, Defstyle);

TODO auto-generated Constructor stub

System.out.println ("2");

Inittext ();

}

Public myprogress (context context, AttributeSet Attrs) {

Super (context, attrs);

TODO auto-generated Constructor stub

System.out.println ("3");

Inittext ();

}

@Override

Public synchronized void setprogress (int progress) {

TODO auto-generated Method Stub

SetText (progress);

Super.setprogress (progress);

}

@Override

protected synchronized void OnDraw (canvas canvas) {

TODO auto-generated Method Stub

Super.ondraw (canvas);

This.settext ();

Rect rect = new rect ();

This.mPaint.getTextBounds (this.text, 0, This.text.length (), rect);

int x = (getwidth ()/1)-Rect.centerx ()-18;

int y = (getheight ()/2)-rect.centery ();

Canvas.drawtext (This.text, x, Y, this.mpaint);

}

Initialize, brush

private void Inittext () {

This.mpaint = new Paint ();

This.mPaint.setColor (Color.White);

}

private void SetText () {

SetText (This.getprogress ());

}

Set text content

private void SetText (int progress) {

int i = (Progress * +)/This.getmax ();

This.text = string.valueof (i) + "%";

}

}

The other is the code inside the actiivty:

public class Progresstest extends Activity {

Private Button btn_go = null;

Private myprogress myprogress = null;

Private Handler Mhandler;

Public TextView Baifen;

/** called when the activity is first created. */

@Override

public void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (R.layout.main);

Findview ();

SetParam ();

AddListener ();

Mhandler = new Handler (new Callback () {

@Override

public boolean handlemessage (Message msg) {

TODO auto-generated Method Stub

Myprogress.setprogress (Msg.what);

return false;

}

});

}

private void Findview () {

Btn_go = (Button) Findviewbyid (R.ID.BTN_GO);

Myprogress = (myprogress) Findviewbyid (R.id.pgsbar);

Baifen = (TextView) Findviewbyid (R.id.baifen);

}

private void SetParam () {

Btn_go.settext ("Start");

}

private void AddListener () {

Btn_go.setonclicklistener (New Onclicklistener () {

@Override

public void OnClick (View v) {

TODO auto-generated Method Stub

New Thread (New Runnable () {

@Override

public void Run () {

TODO auto-generated Method Stub

for (int i = 0; I <=; i++) {

Mhandler.sendemptymessage (i * 2);

try {

Thread.Sleep (100);

} catch (Interruptedexception e) {

TODO auto-generated Catch block

E.printstacktrace ();

}

}

}

}). Start ();

}

});

}

}

There is a need to create a drawable folder under the Res folder; *****.xml, the code is as follows:

<?xml version= "1.0" encoding= "Utf-8"?>

<layer-list xmlns:android= "Http://schemas.android.com/apk/res/android" >

<item android:id= "@android: Id/background" >

<shape>

<corners android:radius= "3dip"/>

<gradient

Android:angle= "270"

android:centery= "0.75"

Android:endcolor= "#999999"

Android:startcolor= "#999999"/>

</shape>

</item>

<item android:id= "@android: Id/secondaryprogress" >

<clip>

<shape>

<corners android:radius= "0dip"/>

<gradient

Android:angle= "270"

android:centery= "0.75"

Android:endcolor= "#23b7a1"

Android:startcolor= "#23b7a1"/>

</shape>

</clip>

</item>

<item android:id= "@android: Id/progress" >

<clip>

<shape>

<corners android:radius= "5dip"/>

<gradient

Android:angle= "270"

android:centery= "0.75"

Android:endcolor= "#23b7a1"

Android:startcolor= "#23b7a1"/>

</shape>

</clip>

</item>

</layer-list>

Under the Values folder, add the code stytles.xml:

<!--custom progress bar--

<style name= "Progressbar_mini" parent= "@android: Style/widget.progressbar.horizontal" >

<item name= "Android:maxheight" >50dip</item>

<item name= "Android:minheight" >12dip</item>

<item name= "Android:indeterminateonly" >false</item>

<item name= "android:indeterminatedrawable" > @android:d Rawable/progress_indeterminate_horizontal</item >

<item name= "android:progressdrawable" > @drawable/progressbar_mini</item>

</style>

Basic all the code I have pasted here, there will be some color values, this you can define your own.

If useful, not clear how to write, you can add me qq:2268214831 or: hanxinghui0817 private chat Me Oh

I have insufficient experience, if there is any mistake also ask the great God a lot of advice, here thank you! Hope this blog to help some people cry!
