Preface

To achieve the subtitle effect by dynamically changing the width attribute of TextView, the result shows that setWidth is not self-occupied. Here we will share the solution.

Body

Go directly to the Code:

Final LayoutParams lp = mLrcTextShadow. getLayoutParams ();
Width + = 5;
Lp. width = width;
MLrcTextShadow. setLayoutParams (lp );

Code Description:

The key is to reset LayoutParams. To obtain LayoutParams, you can put it out of the loop. Set the width first, and then set it.

A problem is also found here. After setting the width dynamically, you need to wait until a word can be fully displayed, and do not write only half the word.
