关于TextView getLineCount问题

今天用getLineCount()方法获取行高失败;

 原因: 

 

public int getLineCount ()

Since: API Level 1

Return the number of lines of text, or returns 0 if the internal Layout has not been built.

 

解决办法:

 

tv.setText("Text Here");
tv.post(new Runnable() {

    @Override
    public void run() {

        int lineCount    = tv.getLineCount();

        Log.v("LINE_NUMBERS", lineCount+"");
    }
});
