Android SeekBar样式修改实现签到效果

1、实现功能 签到的progress 支持气泡指示器
效果图

2、实现代码
（1）重写SeekBar禁止拖动
package com.example.demo;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.SeekBar;

public class MySeekBar extends SeekBar{

public MySeekBar(Context context) {
super(context,null);
}

public MySeekBar(Context context, AttributeSet attrs) {
super(context, attrs, 0);

}

public MySeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);

}

@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
// 原来是要将TouchEvent传递下去的,我们不让它传递下去就行了
// return super.onTouchEvent(event);
return false;
}

}

（2）mainActivity
package com.example.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.LinearLayout;

public class MainActivity extends Activity {
private MySeekBar mySeekBar;
private int speed = 0;//进度条每次点击
private int lin_speed = 0;//上面的描述文字的位置
private LinearLayout ll_des;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mySeekBar = (MySeekBar) findViewById(R.id.seekbar);
Button btn_add = (Button) findViewById(R.id.btn_add);
mySeekBar.setProgress(2);
ll_des = (LinearLayout) findViewById(R.id.ll_des);

btn_add.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
runOnUiThread(new Runnable() {
@Override
public void run() {
if (speed == 2) {
speed = 0;
}
if (speed < 68) {
if (speed == 60) {
speed = speed + 10 – 2;//进度条每次前进十个位置
} else {
speed = speed + 10;//进度条每次前进十个位置
}
if (speed <= 60) {
lin_speed = lin_speed + 120;//组件根据实际组件长宽算出来的
}
LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) ll_des.getLayoutParams();
lp.setMargins(lin_speed, 0, 0, 0);
ll_des.setLayoutParams(lp);
mySeekBar.setProgress(speed);
}
}
});
}
});
}

}
（3）布局

android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:text=”加” />

<LinearLayout
android:layout_width=”match_parent”
android:layout_height=”80dp”
