The method introduced in this paper is simple, fast and practical. Let the editor take you to learn "how to use progressbar in Android with bottom indicator and text progress bar"!

List the source code:

Public class TextProgressBar extends LinearLayout {String text; Paint mPaint; private Rect textRect; private Bitmap bitmap; private ProgressBar progressBar; int progress; int proWidth, proHeight; public TextProgressBar (Context context, AttributeSet attrs, int defStyleAttr) {super (context, attrs, defStyleAttr); initText (context);} public TextProgressBar (Context context) {super (context); initText (context);} public TextProgressBar (Context context, AttributeSet attrs) {super (context, attrs); initText (context) } @ Override protected synchronized void onDraw (Canvas canvas) {super.onDraw (canvas); progress = progressBar.getProgress (); if (progress = = 0 | progress = = progressBar.getMax () return; this.mPaint.getTextBounds (this.text, 0, this.text.length (), textRect); proWidth = progressBar.getWidth (); proHeight = progressBar.getHeight () / / drawing indicator int bitmapx = (int) (progressBar.getLeft () + proWidth * ((progress * 1f) / progressBar.getMax ())-bitmap.getWidth () / 2; int bitmapy = proHeight + bitmap.getHeight () / 2; if (bitmapx

ProgressBar.getRight ()-bitmap.getWidth () bitmapx = progressBar.getRight ()-bitmap.getWidth (); canvas.drawBitmap (bitmap, bitmapx, bitmapy, mPaint); / / write int tvx = (int) (progressBar.getLeft () + proWidth * ((progress * 1f) / progressBar.getMax ())-textRect.centerX (); int tvy = proHeight + bitmap.getHeight () * 2 + 4; if (tvx)

= progressBar.getRight ()-textRect.width () tvx = progressBar.getRight ()-textRect.width (); canvas.drawText (this.text, tvx, tvy + bitmap.getHeight (), this.mPaint);} / / initialize, brush private void initText (Context context) {View inflate = View.inflate (context, R.layout.textprogressbar, this); progressBar = (ProgressBar) inflate.findViewById (R.id.progressbar1); progressBar.setProgress (50); setWillNotDraw (false); this.mPaint = new Paint () This.mPaint.setColor (getResources (). GetColor (R.color.red)); this.mPaint.setTextSize (20); textRect = new Rect (); text = "0"; bitmap = BitmapFactory.decodeResource (context.getResources (), R.mipmap.progress_top);} public void setProgress (int progress) {progressBar.setProgress (progress);} public void setText (String str) {text = str }} at this point, I believe you have a deeper understanding of "how to use progressbar to achieve with a bottom indicator and text progress bar in Android".
