How to set maxLines and ellipsize of a TextView at the same time
提问by michael
I want to limit my text view to have maximum of 5 lines, so I did:
我想将我的文本视图限制为最多 5 行，所以我做了：
<TextView
android:id="@+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:maxLines="5" />
But when I try to configure it to add '...' when the text is truncated, I add android:ellipsize="end". I do see the ... but then my TextView only has a max line of 2, instead of 5.
但是当我尝试将其配置为在文本被截断时添加 '...' 时，我添加了 android:ellipsize="end"。我确实看到了...但是我的 TextView 最多只有 2 行，而不是 5 行。
Can you please suggest how can I make the text view of maximum line of 5 and add '...' when it get truncated?
您能否建议我如何制作最多 5 行的文本视图并在它被截断时添加“...”？
Thank you.
谢谢你。

Progrmatically, you can use:
以编程方式，您可以使用：
your_text_view.setEllipsize(TextUtils.TruncateAt.END);
your_text_view.setMaxLines(4);
your_text_view.setText("text");

try this code...
试试这个代码...
final TextView tv_yourtext = (TextView)findViewById(R.id.text);
tv_yourtext.setText("A really long text");
ViewTreeObserver vto = tv_yourtext.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
ViewTreeObserver obs = tv_yourtext.getViewTreeObserver();
obs.removeGlobalOnLayoutListener(this);
if(tv_yourtext.getLineCount() > 6){
Log.d("","Line["+tv_yourtext.getLineCount()+"]"+tv_yourtext.getText());
int lineEndIndex = tv_yourtext.getLayout().getLineEnd(5);
String text = tv_yourtext.getText().subSequence(0, lineEndIndex-3)+"...";
tv_yourtext.setText(text);
Log.d("","NewText:"+text);
}
}
});

You only need to add this line to your TextView:
您只需要将此行添加到您的 TextView：
android:ellipsize="marquee"

Apparently you have to specify the inputTypeand set it to nonein this case.
It should look something like this:
显然inputType，none在这种情况下，您必须指定并将其设置为。它应该是这样的：
<TextView
android:ellipsize="end"
android:inputType="none"
android:maxLines="2"

<TextView
android:id="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxLines="5"
android:ellipsize="end" />
Works for me, make sure TextView top container should have height like
对我有用，确保 TextView 顶部容器的高度应该像
android:layout_height="wrap_content"
回答by david72
When I set the TextView height to a constant value (like 50dp), it works fine for me.
当我将 TextView 高度设置为常量值（如 50dp）时，它对我来说效果很好。
