如何在LinearLayout中正确设置多行TextView省略号

Question

I have such a layout hierarchy as following:

<LinearLayout
    android:id="@+id/wrapper"
    android:layout_width="50dp"
    android:layout_height="63dp"
    android:orientation="vertical">

<TextView
    android:id="@+id/title"
    android:background="#f00"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="title"
    />

<TextView
    android:id="@+id/detail"
    android:background="#0f0"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="afasdfasdfasfasdfasfdasfasdfasfasdfsadfasfasdfasdfasdf"
    />

</LinearLayout>

The result view is like this:

The wrapper LinearLayout's height is going to be dynamically changed.So it is not fixed to 63dp.The fact is that the detail is being cut which doesn't satisfy my need.What I want is that the last complete visible line is changed to "XXX...".Like this:

From my code,I will change LinearLayout's height dynamically.

LinearLayout wrapper = (LinearLayout)findViewById(R.id.wrapper);

wrapper.getLayoutParams().height = // dynamical height;

Answer 1

Your best bet is to utilize the maxLines and ellipsize attributes.

<TextView
  android:id="@+id/detail"
  android:background="#0f0"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:maxLines="2"
  android:ellipsize="end"
  android:text="afasdfasdfasfasdfasfdasfasdfasfasdfsadfasfasdfasdfasdf"
/>

Answer 2

将android:layout_height="63dp"更改为android:layout_height="wrap_content"
