新建一个CustomView继承TextView并实现4个构造方法
public class MyTextView extends TextView{
public MyTextView(Context context) {
super(context);
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public MyTextView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
//控件获取焦点
@Override
public boolean isFocused() {
return true;
}
}
XML布局内控件
//定义两个组定义的TextView
<com.example.customview.MyTextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:singleLine="true"
android:text="@string/niu" />
<com.example.customview.MyTextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView1"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:singleLine="true"
android:text="@string/niu" />
