[英]How to set scroll view by programmatically in Android?
I want to set the scroll view height, width, margin and set at below the text view and at the right of relative layout. 我想设置滚动视图的高度,宽度,边距,并设置在文本视图下方和相对布局的右侧。 I tried to set only height of scroll view dynamically.
我试图仅动态设置滚动视图的高度。 But how to set margin of scroll view and how to keep it programmatically at:
但是如何设置滚动视图的边距以及如何以编程方式将其保持在:
android:layout_below="@+id/item_textInspectorName"
android:layout_toRightOf="@+id/rel_out_two"
Here is my XML code 这是我的XML代码
<RelativeLayout> ................
<ScrollView
android:id="@+id/scrollExpand"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_below="@+id/item_textInspectorName"
android:layout_toRightOf="@+id/rel_out_two"
android:layout_marginLeft="7.5dp"
android:layout_marginRight="10dp"
android:layout_marginTop="6dp"
android:background="@android:color/white"
android:fillViewport="true">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.example.tazeen.classnkk.ExpandableTextView
android:id="@+id/expandable_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:ellipsize="end"
android:text="expand"
android:textColor="@android:color/black"
android:textSize="12sp"
android:textStyle="normal" />
</LinearLayout>
</ScrollView>
</RelativeLayout> ................
And here is my Activity code which is set the height of dynamically . 这是我的Activity代码,该代码动态设置了高度。
ExpandableTextView txtRemark = (ExpandableTextView)findViewById(R.id.expandable_text);
int strRemarkLength = strRemark.length();
if(strRemarkLength > 100)
{
txtRemark.setText(strRemark.concat(" ...Less"));
Log.e("", " Lesss !!!");
scrollView.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT, 350));
}
else
{
txtRemark.setText(strRemark);
Log.e("", "Not Lesss !!!");
}
