检查TextView的是Android ellipsized [英] Check if textview is ellipsized in android

问题描述

我的TextView 与宽度包装内容。在这种的TextView 我设置文本​​，但每次文字是相同长度的不行。当文字很长，我用单行真实和 ellipsize ：结束。但现在我有一个问题。我想设置的其他布局可见，但是依赖于长我的文字。如果文本太长，以适应我要调用setVisible真实画面，但是当文字很短，当我不需要ellipsize，我想设置知名度假。所以，我需要检查我的TextView的状态。当其ellipsize我想调用setVisible true，则它不是调用setVisible 假的。我怎样才能做到这一点。
这是我得到了什么：

I have TextView with width as wrap content. In this TextView I set text, but text is not of the same length every time. When text is very long I use single line true and ellipsize: end. But now I have a problem. I want to set Visibility of other layout but that depends on the length my text. If text is too long to fit in the screen I want to setVisible true, but when text is short and when I don't need ellipsize, I want to set visibility false. So I need to check status of my TextView. When its ellipsize I want to setVisible true, when its not setVisible false. How I can do that. This is what I got:

tvAle.post(new Runnable() {

        @Override
        public void run() {

            int lineCount    = tvAle.getLineCount();
            Paint paint =  new Paint();
            paint.setTextSize(tvAle.getTextSize());
            final float size = paint.measureText(tvAle.getText().toString());
            Log.v("a", ""+size+" "+tvAle.getWidth());
            if ((int)size > (tvAle.getWidth()+10)) {
                allergiesLayout.setVisibility(View.VISIBLE);
            }

            else
                allergiesLayout.setVisibility(View.GONE);

        }

但是这种解决方案是行不通的。

but this solution doesn't work.

推荐答案

您可以使用提供此方法：<一href=\"http://developer.android.com/reference/android/text/StaticLayout.html#getEllipsisCount%28int%29\">getEllipsisCount

You can use this method provided: getEllipsisCount

Layout layout = textview1.getLayout();
if(layout != null) {
    int lines = layout.getLineCount();
    if(lines > 0) {
        int ellipsisCount = layout.getEllipsisCount(lines-1);
        if ( ellipsisCount > 0) {
            Log.d(TAG, "Text is ellipsized");
        } 
    } 
}

在这里可通过getLineCount得到线（）

where line could be obtained via getLineCount()
