TextView cuts off text when it is long enough

问题:

I have strange problem with TextView, it cuts off part of the text at the end. My layout looks like

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="top|center_horizontal"
        android:gravity="top|center_horizontal"
        android:orientation="vertical" >
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_gravity="top|center_horizontal"
            android:gravity="top|center_horizontal"
            android:orientation="horizontal"
            android:layout_weight="1"
            android:layout_marginBottom="5dp">
            <Button
                android:id="@+id/btnPreviousQuestion"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/selector_arrow_left"
                android:clickable="true"
                android:visibility="gone" >
            </Button>
            <TextView
                android:id="@+id/txtQuestion"
                style="@style/question_text"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:gravity="top|center_horizontal"
                android:layout_weight="1"
                 />
            <Button
                android:id="@+id/btnNextQuestion"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginRight="10dp"
                android:background="@drawable/selector_arrow_right"
                android:clickable="true" >
            </Button>
        </LinearLayout>
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_weight="1"
            android:orientation="horizontal" >
            <WebView
                android:id="@+id/wvMultimediaQuestion"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom|center_horizontal"
                android:layout_marginLeft="50dp"
                android:layout_marginRight="55dp"
                android:layout_weight="1"
                android:visibility="gone" />
        </LinearLayout>
    </LinearLayout>

and txtQuestion cuts off text when it is long enough. What is wrong, does anybody know ?

回答1:

Make use of these attributes

    android:lines="1"
    android:scrollHorizontally="true"
    android:ellipsize="end"

will append "..." at the end. But this will not solve problem in honeycomb tab

So for honeycomb tablet add the following atttibute also

android:singleLine="true" 

On the other hand if you require marquee effect

android:singleLine="true"
android:ellipsize="marquee" 
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true" 
android:focusable="true" 
android:focusableInTouchMode="true

回答2:

Yes there are some attributes you need to set, but first let us know what type of textview do you want exactly, single line or multi line?

There are some attributes you can take care of:

android:singleLine="true"  // or false
android:ellipsize="marquee"   // must check
android:lines="1"

回答3:

You need to set android:minLines="2"

回答4:

If you expect differing lengths of text for your view or you're going to change the textSize of different instances of your TextView then you should use View.addOnLayoutChangeListener().
