FastTextView use StaticLayout to render Spanned String, so it support most features of Android TextView. Inspired by : https://engineering.instagram.com/improving-comment-rendering-on-android-a77d5db3d82e http://ragnraok.github.io/textview-pre-render-research.html ## Features 1.Faster than Android TextView 2.More flexibility 3.Support Stroke Text (More accurate method to measure stroke text and italic text) 4.Correct Ellipsis handle with ImageSpan ![](ellipsis.png) 5.Custom Read More Support ![](readmore.gif) ## FastTextView vs Android TextView Rendering a SpannableString of 389 chars with ClickableSpan and ImageSpan. Call 'onMeasure'、'onDraw' 1000 times. Here are the test results on MI MAX (Android 6.0.1): ``` D/FastTextLayoutView: FastTextLayoutView onMeasure cost:0 D/FastTextView: FastTextView onMeasure cost:1 D/TestTextView: TestTextView measure cost:104 D/FastTextLayoutView: FastTextLayoutView onDraw cost:271 D/FastTextView: FastTextView onDraw cost:250 D/TestTextView: TestTextView onDraw cost:249 ``` You can see FastTextView's 'onMeasure' almost no time consuming. ## Basic Usage ``` repositories { ... jcenter() ... } dependencies { ... compile 'com.lsjwzh.widget:FastTextView:1.2.15' ... } ``` java code ``` FastTextView fastTextView = (FastTextView) mRootView.findViewById(R.id.fast_tv2); fastTextView.setText(spannableString); ``` ## Advance Usage ### Use Layout directly java code ``` TextPaint textPaint = new TextPaint(); textPaint.setAntiAlias(true); textPaint.setColor(Color.WHITE); float textSize = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_SP, 20, getResources().getDisplayMetrics()); textPaint.setTextSize(textSize); FastTextLayoutView fastTextLayoutView = (FastTextLayoutView) mRootView.findViewById(R.id.fast_tv); int width = Layout.getDesiredWidth(spannableStringBuilder, textPaint); StaticLayout layout = new StaticLayout(spannableStringBuilder, textPaint, Math.min(width, getResources().getDisplayMetrics().widthPixels), Layout.Alignment.ALIGN_NORMAL, 1.0f, 0.0f, true); fastTextLayoutView.setTextLayout(layout); ``` ### Single Line Stroke Text java code ``` ... ... StrokeSpan strokeSpan = new StrokeSpan(Color.BLUE, Color.YELLOW, 20); spannableStringBuilder.setSpan(strokeSpan, 0, spannableStringBuilder.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE); FastTextView fastTextView = (FastTextView) mRootView.findViewById(R.id.fast_tv2); fastTextView.setText(spannableStringBuilder); ``` ### Read More ``` ReadMoreTextView readMoreTextView = (ReadMoreTextView) mRootView.findViewById(R.id.readmore_tv); readMoreTextView.setText(spannableStringBuilder); readMoreTextView.setCustomEllipsisSpan(new ReadMoreTextView.EllipsisSpan(" Read More")); readMoreTextView.setCustomCollapseSpan(new ReadMoreTextView.EllipsisSpan(" Collapse")); ``` # Build Project https://github.com/anggrayudi/android-hidden-api You should use 'android-hidden-api' to build project. 1.Go to /platforms/. 2.Copy, paste and replace the downloaded hidden API file into this directory, e.g. android-25/android.jar. 3.Change compileSdkVersion and targetSdkVersion to 25 (for example). 4.Finally, rebuild your project. # TODO List 1.Layout Cache (For List Scene) 2.ColorState background 3.ReadMore 4.Ellipsis 5.AutoSize 6.ColorState textColor # License ``` Copyright 2017 lsjwzh Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
