最近做了一个圆形进度条控件 顺便就把他抽出来哒直接贴出代码了 类中提供了各种颜色的设置 字体大小 已经进度的宽度 加上了进度回调(虽然感觉没啥卵用)
这是自定义的类 就这么一个类咯

import android.graphics.Canvas;
import android.graphics.Color;

* ps: 圆环会自动根据宽度高度取小边的大小的比例 你也可以自己设置圆环的大小@see #scrollBy(int, int)

下面是简单的调用类了啊
package com.example.progress;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Handler;
/**
* 测试类
*
* @author yung7086 2015年12月9日 21:51:49
*/
public class MainActivity extends Activity {
private int preColor = Color.parseColor("#2c2200");
private int progressColor = Color.parseColor("#6bb849");
private int CircleColor = Color.parseColor("#CCCCCC");
private int textColor = Color.parseColor("#9bb879");;
private CircleProgress pv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pv = (CircleProgress) findViewById(R.id.progressview1);
pv.setTextColor(textColor).setCircleBackgroud(CircleColor)
.setPreProgress(progressColor).setProgress(preColor)
.setProdressWidth(50).setPaddingscale(0.8f);
han.sendEmptyMessageDelayed(1, 100);
}
Handler han = new Handler() {
public void handleMessage(android.os.Message msg) {
pv.setValue(msg.what);
han.sendEmptyMessageDelayed(msg.what + 1, 100);
};
};
}
布局文件很明显没啥
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.progress.MainActivity" >
<com.example.progress.CircleProgress
android:id="@+id/progressview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffff"
android:text="@string/hello_world" />
</RelativeLayout>
草草的写了下 ..尊重作者 yung7086
