有些时间没来写了 ，接下来继续分享下本姑娘写的水平进度条，望能帮到初学者~~~
MainActivity 类

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.Menu;
import android.view.MenuItem;

private TextView textnumber;
private int num;
private int progress=0;
private Message message;
CustomProgressBar bar;
private Handler handler=new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
int p=msg.what;
//mPbar.setProgress(p);
bar.setProgress(p);
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textnumber = (TextView)findViewById(R.id.textnumber);
num = (int) (Math.random()*100);
textnumber.setText(String.valueOf(num+"/100").toString());
//拿到自定义的进度条
bar = (CustomProgressBar) findViewById(R.id.item_progress_SeekBar);
//设置进度条的最大值
bar.setMax(100);
//设置进度值
bar.setProgress(60);
//开启线程
new Thread(yuanlirunnable).start();
}
Runnable yuanlirunnable=new Runnable() {
@Override
public void run() {
message=handler.obtainMessage();
try {
for (int i = 0; i <= 100; i++) {
/*
* 在这里控制进度
*/
//int x=++progress;
//int randomnumberprogress=(int) (Math.random()*100);
//int x=randomnumberprogress;
int x=num;
message.what=x;
handler.sendEmptyMessage(message.what);
Thread.sleep(100);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
CustomProgressBar类

}
public CustomProgressBar(Context context, AttributeSet attrs, int defStyle) {
this(context, attrs, defStyle,0);
}
public CustomProgressBar(Context context, AttributeSet attrs, int defStyle, int styleRes) {
super(context, attrs, defStyle);
}
@Override
protected synchronized void onMeasure(int widthMeasureSpec,int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
//进度条圆角度
public final int roundCorners = 15;
Shape getDrawableShape() {
final float[] roundedCorners = new float[] { 0, 0, 0, 0, 0, 0, 0, 0 };
for(int i=0;i<roundedCorners.length;i++){
roundedCorners[i] = dp2px(getContext(), roundCorners);
}
return new RoundRectShape(roundedCorners, null, null);
}
/**dp转换成px*/
public static float dp2px(Context context, float dp) {
final float scale = context.getResources().getDisplayMetrics().density;
return dp * scale;
}
}
