TextViewexpTextView;

@Bind(R.id.progressbar_layout)

LinearLayoutprogressbarLayout;

private intmProgress;

private intmMax;

publicMyProgressBar(Context context) {

}

if(max !=mMax) {

mMax= max;

postInvalidate();

if(mProgress> max) {

mProgress= max;

}

refreshProgress();

}

}

public synchronized voidsetProgress(intprogress) {

if(progress ==mProgress) {

// No change from current.

return;

}

mProgress= progress;

refreshProgress();

}

private voidrefreshProgress() {

floatscale =mMax>0? (float)mProgress/ (float)mMax:0;

//TODO: 当要使用 weight 时 width 必须设置成 0
