我正在尝试使用@ + id / trackname和@ + id / artist_and_album来使用以下布局中的选取框设置,但它们不会滚动。我也尝试在实际的Activity中使用setSelected(true)和setFocusable(true),但是没有用。这是布局的图片:

我的活动中还包括以下几行:
mTrackName = (TextView) findViewById(R.id.trackname);
mTrackName.setSelected(true);
mArtistAndAlbumName = (TextView) findViewById(R.id.artist_and_album);
mArtistAndAlbumName.setSelected(true);
看起来嵌套RelativeLayout的原始布局阻止了文本滚动。
答案 1 :(得分:1)
单独的类文件:
public class TextScrolling extends TextView {
public TextScrolling(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public TextScrolling(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TextScrolling(Context context) {
super(context);
}
@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(focused)
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public void onWindowFocusChanged(boolean focused) {
if(focused)
super.onWindowFocusChanged(focused);
}
@Override
public boolean isFocused() {
return true;
}
}
在你的xml文件中执行以下操作:
<yourpakage name.aboveclassname
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textStyle="bold|italic"
android:id="@+id/scrolltext"
android:padding="5dip"
android:textSize="15dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
当然这会奏效。试试吧......
答案 2 :(得分:0)
这是我的字幕代码:
<TextView
android:id="@+id/scanCode"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:lines="1"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#ffffff" />
也在代码中设置:
scanCode.setEnabled(true);
scanCode.setSelected(true);
答案 3 :(得分:0)
设置focusable(true)并在代码调用requestFocus()中; 如果您的布局包含其他具有可聚焦(true)的视图,则应确保您的textview具有焦点
答案 4 :(得分:0)
试 的setSelected(真) 在settext之后
答案 5 :(得分:0)
设置代码
yourTexView.setMovementMethod(new ScrollingMovementMethod());
