Android 自定义带数字的圆形进度条和中间是文字的圆形进度条View

这是一个自定义带数字的圆形进度条和中间是文字的圆形进度条View。自定义View的基本流程在这里就不多说了。（效果图在最后）

自定义View分好几种。我这个Demo主要用到了自己绘画的和组合的View。

首先看怎么自定义带数字的圆形进度条的View。注解读写在代码里了，在这里不多说。

类MyCirclePB自定义的View。具体代码如下：

package com.yehu.z01_circlepb;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.SystemClock;
import android.util.Log;
import android.view.View;
import android.widget.Toast;

import com.yehu.z01_circlepb.My_Cricle.My_CricleListern;

public class MainActivity extends Activity {

<span style="white-space:pre">	</span>private My_Cricle my_Cricle;
<span style="white-space:pre">	</span>private MyCirclePB myCirclePB;
<span style="white-space:pre">	</span>String[] strs = { "从未超越", "超越自我", "旗鼓相当" };

<span style="white-space:pre">	</span>@Override
<span style="white-space:pre">	</span>protected void onCreate(Bundle savedInstanceState) {
<span style="white-space:pre">		</span>super.onCreate(savedInstanceState);

<span style="white-space:pre">		</span>myCirclePB.setOnClickListener(new View.OnClickListener() {

<span style="white-space:pre">			</span>@Override

<span style="white-space:pre">				</span>}.start();
<span style="white-space:pre">			</span>}
<span style="white-space:pre">		</span>});
<span style="white-space:pre">		</span>// 文本 圆形框

<span style="white-space:pre">	</span>};

}

自定义带数字的圆形进度条View基本就完事了。写一个XML布局就可以使用了。在这里就不单个写了，布局都整合在一起了，后面补上。

这个是一个组合View。

先写布局吧！my_cricle.xml布局如下：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<com.yehu.z01_circlepb.MyCirclePB
android:id="@+id/mycirlepb"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp" />

<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:orientation="vertical" >

<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="aaa" />

<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="18sp"
android:text="aaaa" />

<TextView
android:id="@+id/text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="aaa" />
</LinearLayout>

</RelativeLayout>

类My_Cricle具体代码如下：

package com.yehu.z01_circlepb;

import android.content.Context;
import android.graphics.Color;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.RelativeLayout;
import android.widget.TextView;

public class My_Cricle extends RelativeLayout {

private Context context;
private View v;
private TextView text2;
private MyCirclePB myCirclePB;

public MyCirclePB getMyCirclePB() {
return myCirclePB;
}

/**
* 这里写一些事件的回调
* @author sunmj
*
*/
public interface My_CricleListern {
public void back(String name);
}

public My_Cricle(Context context) {
this(context, null);
init(context);
}

public My_Cricle(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);

}

private void init(Context context) {
// TODO Auto-generated method stub
this.context = context;
v = LayoutInflater.from(context).inflate(R.layout.my_cricle, this, true);
text2 = (TextView) v.findViewById(R.id.text2);
}

/**
* 这个方法里面写一些配置的文件例如
*/
public void init_view() {
myCirclePB = (MyCirclePB) v.findViewById(R.id.mycirlepb);
int n = 100;
myCirclePB.setMax(n);
myCirclePB.setRoundColor(Color.GRAY);
myCirclePB.setRoundProgressColor(Color.RED);
myCirclePB.setRoundWidth(40);
myCirclePB.setProgress(0);
myCirclePB.setShowProgress(false);

}

public TextView getText2() {
return text2;
}

//回调回去
public void set_listern(My_CricleListern nCricleListern)
{
nCricleListern.back("1111");
}
}

到这里基本就实现了带数字的圆形进度条，和中间是文字的圆形进度条。下面就是具体的使用了。

主布局activity_main.xml如下：

<LinearLayout 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"
android:gravity="center_horizontal"
android:orientation="vertical" >

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="圆形进度条"
android:textSize="16sp" />

<com.yehu.z01_circlepb.MyCirclePB
android:id="@+id/my_criclePB"
android:layout_width="240dp"
android:layout_height="200dp" />

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="圆形文本框"
android:textSize="16sp" />

<com.yehu.z01_circlepb.My_Cricle
android:id="@+id/my_cricle"
android:layout_width="180dp"
android:layout_height="220dp" />

</LinearLayout>

类MainActivity具体代码如下：

package com.yehu.z01_circlepb;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.SystemClock;
import android.util.Log;
import android.view.View;
import android.widget.Toast;

import com.yehu.z01_circlepb.My_Cricle.My_CricleListern;

public class MainActivity extends Activity {

private My_Cricle my_Cricle;
private MyCirclePB myCirclePB;
String[] strs = { "从未超越", "超越自我", "旗鼓相当" };

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 圆形进条
myCirclePB = (MyCirclePB) findViewById(R.id.my_criclePB);
myCirclePB.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
myCirclePB.setEnabled(false);
new Thread() {
public void run() {
int n = 1000;
myCirclePB.setMax(n);
for (int i = 0; i <= n; i++) {
Log.e("TAG", "download i=" + i);
myCirclePB.setProgress(i);
if (myCirclePB.getProgress() == myCirclePB.getMax()) {
handler.sendEmptyMessage(2);
}
SystemClock.sleep(5);
}
};
}.start();
}
});
// 文本 圆形框
my_Cricle = (My_Cricle) findViewById(R.id.my_cricle);
my_Cricle.init_view();
my_Cricle.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
my_Cricle.setEnabled(false);
final MyCirclePB circlePB = (MyCirclePB) (((My_Cricle) v)
.getMyCirclePB());
new Thread() {
public void run() {
int n = 1000;
circlePB.setMax(n);
for (int i = 0; i <= n; i++) {
Log.e("TAG", "download i=" + i);
circlePB.setProgress(i);
String str = null;
Message msg = Message.obtain();
if (circlePB.getProgress() < circlePB.getMax() / 3) {
str = strs[0];

msg.what = 3;
} else if (circlePB.getProgress() < circlePB
.getMax() * 2 / 3) {
str = strs[1];
msg.what = 4;
} else {
str = strs[2];
msg.what = 5;
}
msg.obj = str;
handler.sendMessage(msg);
if (circlePB.getProgress() == circlePB.getMax()) {
handler.sendEmptyMessage(1);
}
SystemClock.sleep(5);
}
};
}.start();
}
});
}

private Handler handler = new Handler() {
public void handleMessage(android.os.Message msg) {
String str = (String) msg.obj;
int flag = msg.what;
if (flag == 1) {
my_Cricle.setEnabled(true);
} else if (flag == 2) {
myCirclePB.setEnabled(true);
} else if (flag == 3) {
my_Cricle.getText2().setText(str);
my_Cricle.getText2().setTextColor(0xffff0000);
} else if (flag == 4) {
my_Cricle.getText2().setText(str);
my_Cricle.getText2().setTextColor(0xff0000ff);
} else if (flag == 5) {
my_Cricle.getText2().setText(str);
my_Cricle.getText2().setTextColor(0xff00ff00);
}
};
};

}

代码的不怎么简洁，一直在努力中……
