You do not need to worry 8 | about the `emoji` truncated cause garbled, and you also do not need to worry 9 | about the text be affected by the class `CharacterStyle` and its subclass 10 | truncated cause unexpected result. 11 | 12 | The EllipsizeTextView extends TextView, it supports multiple lines omit 13 | redundant characters, but the method `{@link EllipsizeTextView#setMaxLines(int)}` 14 | will be always needed to call. besides, you can call the method 15 | `{@link EllipsizeTextView#setEllipsizeText(CharSequence, int)}` to custom 16 | the content, style, and index(in the reverse order) of the ellipsis. 17 | #### Preview 18 | ![](https://raw.githubusercontent.com/dinuscxj/EllipsizeTextView/master/Preview/EllipsizeTextView.gif?width=300) 19 | 20 | ## Installation 21 | 22 | Add the following dependency to your build.gradle file: 23 | ```gradle 24 | dependencies { 25 | compile 'com.dinuscxj:ellipsizetextview:1.0.5' 26 | } 27 | ``` 28 | 29 | ## Usage 30 | 31 | ### Normal Mode 32 | You can specify the attributes from a layout XML like: 33 | ```xml 34 | 43 | ``` 44 | Or from code like: 45 | 46 | ```java 47 | mEllipsizeText.setMaxLines(2); 48 | mEllipsizeText.setEllipsizeText(ellipsizeText, 8); 49 | mEllipsizeText.setText(R.string.long_text); 50 | ``` 51 | 52 | ### Auto Mode 53 | the diff from Normal Mode is that you should set the attribute `android:layout_height` 54 | to a accurate value and the attribute `android:maxLines` is optional. 55 | 56 | ```xml 57 | 65 | ``` 66 | 67 | Or from code like: 68 | 69 | ```java 70 | mEllipsizeText.getLayoutParams().height = 50dp; 71 | mEllipsizeText.setEllipsizeText(ellipsizeText, 8); 72 | mEllipsizeText.setText(R.string.long_text); 73 | ``` 74 | 75 | ## License 76 | 77 | Copyright 2015-2019 dinus 78 | 79 | Licensed under the Apache License, Version 2.0 (the "License");
