I want to put only text in tab bar, no image... I want to center text in a tab bar, horizontally and vertically. Exactly in the center.
If someone still interested in simple solution without creating own layout and styles:
Use android.widget.TabHost.TabSpec#setIndicator(CharSequence label) for each added tab
Use next code to center and wrap text inside the tab:
int tabCount = tabHost.getTabWidget().getTabCount();
for (int i = 0; i < tabCount; i++) {
final View view = tabHost.getTabWidget().getChildTabViewAt(i);
if ( view != null ) {
// reduce height of the tab
view.getLayoutParams().height *= 0.66;
// get title text view
final View textView = view.findViewById(android.R.id.title);
if ( textView instanceof TextView ) {
// just in case check the type
// center text
((TextView) textView).setGravity(Gravity.CENTER);
// wrap text
((TextView) textView).setSingleLine(false);
// explicitly set layout parameters
textView.getLayoutParams().height = ViewGroup.LayoutParams.FILL_PARENT;
textView.getLayoutParams().width = ViewGroup.LayoutParams.WRAP_CONTENT;
}
}
}
You can add this to xml layout android:gravity="center" or android:layout_gravity="center"
<android.support.design.widget.TabLayout
app:tabMode="fixed"
app:tabContentStart="0dp"
Try this it will be help to you !!!
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="1dp" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="60dp"
android:layout_alignParentBottom="true" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="1dp" >
</FrameLayout>
You can add the following line to the Tab layout to align the text to the center.
app:tabGravity="fill"

I am adding inflate layout dynamically in linear layout,i need to set layout center based on number of layouts.suppose if layouts are two , then it start showing from center.
following is my xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<HorizontalScrollView
android:id="#+id/hsv_category_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:scrollbars="none">
<LinearLayout
android:id="#+id/ll_placeHolder"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:orientation="horizontal">
</LinearLayout>
</HorizontalScrollView>
</RelativeLayout>
and following are my class
public class ScrollTest extends Activity {
HorizontalScrollView hsv_category_list;
LinearLayout ll_placeHolder;
View layoutView[];
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.scroll_test);
hsv_category_list = (HorizontalScrollView)
findViewById(R.id.hsv_category_list);
ll_placeHolder = (LinearLayout) findViewById(R.id.ll_placeHolder);
layoutView = new View[2];
for (int i = 0; i < 2; i++) {
layoutView[i] =
LayoutInflater.from(this).inflate(R.layout.category_list_item, null);
layoutView[i].setId(i);
View parent = layoutView[i].findViewById(i);
TextView tvTime = (TextView)
parent.findViewById(R.id.tv_arrival_time);
tvTime.setText("" + i);
ll_placeHolder.setGravity(Gravity.CENTER);
ll_placeHolder.addView(layoutView[i]);
}
}
}
i need to set the inflate layout start from center.
Please help me to solve this.Thank you.
Set layout gravity to center_horizontal in xml file like this
<LinearLayout
android:id="#+id/ll_placeHolder"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:gravity="center_horizontal"
android:layout_gravity="center"
android:orientation="horizontal">
</LinearLayout>
I have a slight problem getting my layout_weight to work. I am creating a custom bottomBar. But i cant make it to stretch as i want it to.
Bottom Bar View
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/bottom_bar_root"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/bottom_bar_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="4"
android:orientation="horizontal"/>
</RelativeLayout>
This is the big container i am adding my buttons (items) to.
Bottom Bar Item
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1">
<android.support.v7.widget.AppCompatImageView
android:id="#+id/bottom_bar_item_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#android:drawable/arrow_up_float"/>
<TextView
android:id="#+id/bottom_bar_item_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEXT"/>
</LinearLayout>
This is my items that i add dynamically to the view. But somehow the view is not stretched properly.
But when i hardcode it in. It works. So could it be that layout weight does not work dynamically?
How i add the views (items)
private void updateItems(final List<BottomBarTab> bottomBarTabs) {
if (bottomBarTabs.size() < TABS_COUNT) {
throw new RuntimeException("Not enough buttons for bottomBar");
}
for (int i = 0; i < TABS_COUNT; i++) {
bottomBarTabs.get(i).setOnClickListener(this);
bottomBarTabs.get(i).prepareLayout();
container.addView(bottomBarTabs.get(i));
}
}
Screenshot
LayoutWeight is given to inner components of layout only not on parent Linearlayout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="0dp"
android:layout_height="match_parent"
android:weightSum="2">
<android.support.v7.widget.AppCompatImageView
android:id="#+id/bottom_bar_item_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#android:drawable/arrow_up_float"/>
<TextView
android:id="#+id/bottom_bar_item_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="TEXT"/>
</LinearLayout>
public void prepareLayout() {
View view = inflate(getContext(), R.layout.bottom_bar_item,this);
LinearLayout.LayoutParams params =
new LayoutParams(0,LayoutParams.MATCH_PARENT,LAYOUT_WEIGHT);
view.setLayoutParams(params);
if(backgroundColor != null) {
view.setBackgroundColor(backgroundColor);
}
TextView titleText = (TextView) view.findViewById(R.id.bottom_bar_item_text);
titleText.setText(title);
AppCompatImageView imageView = (AppCompatImageView) view.findViewById(R.id.bottom_bar_item_icon);
imageView.setImageResource(iconResId);
}
I changed in my prepareLayout function and put new layoutParams. Because somehow after inflation. The view ignores the weight that was set to it. So i had to force it by code. Maybe this is a android bug?
LinearLayout lay1 = (LinearLayout) findViewById(R.id.lay1);
for(int i=0;i<list1.size();i++) {
View child = lay1.getChildAt(i);
LinearLayout lay3 = (LinearLayout) child.findViewById(R.id.lay3);
for (j = 0; j <list2.size(); j++) {
View child1 = lay3.getChildAt(j);
// View hiddenInfo11 = getActivity().getLayoutInflater().inflate(R.layout.add_inner_item, lay3 , false);
final TextView name = (TextView) child1.findViewById(R.id.name);
name.setText("new");
}
}

Added View Dynamically using the following method.
for(int i=0;i<list.size();i++) {
View hiddenInfo = getActivity().getLayoutInflater().inflate(R.layout.add_item, lay, false);
LinearLayout lay3 = (LinearLayout) hiddenInfo.findViewById(R.id.lay3);
lay1.addView(hiddenInfo);
for (j = 0; j < list2.size(); j++) {
View hiddenInfo1 = getActivity().getLayoutInflater().inflate(R.layout.add_inner_item, lay3, false);
final TextView name = (TextView) hiddenInfo1.findViewById(R.id.name);
name.setText(list2.get(j).get("Name"));
lay3.addView(hiddenInfo1);
}
I have one Layout with creating dynamically and I want to update the child textview from outside of the button click view.I have tried this code.But nothing is changed.Can anyone give suggestion to this sample.
You are looking for "lay2" inside the "lay1" container. According to your XML layout, they are not nested, so you won't be able to find it this way. Change it to this:
LinearLayout lay2 = (LinearLayout) findViewById(R.id.lay2);
You should get the actual lay2 container. I'm not sure whether the text views are there though since I have seen your code for the views' creation.
EDIT:
I've not specified a parent - you should use the Activity for this. Something like:
LinearLayout lay2 = (LinearLayout) MyActivity.this.findViewById(R.id.lay2);
I have the following layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="#f00"
android:id="#+id/main_layout">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#0f0"
android:id="#+id/bed_list"/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00f"
android:text="Howdy cowboy?"
android:textSize="50dip"
android:textColor="#fff"
android:id="#+id/textview"/>
</LinearLayout>
I want to add some textviews to R.id.bed_list (as if they were vertical tabs)
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.main);
LinearLayout bedList = (LinearLayout) findViewById(R.id.bed_list);
for (int i = 0; i < 12; i++) {
System.out.println("In the loop");
TextView textView = new TextView(this);
textView.setText("HJM-" + i);
textView.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
textView.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
bedList.addView(textView,i,
new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
}
}
So far, the code is run, the System.out.println messages in the loop appear at the console, but I only see the textview (R.id.textview). I wanted the list to appear at the left of the screen with the options calculated, but it does not work.
Further on, if I define a first textview in the label (so that there is some items at the very beginning and a space is reserved), I get to see that textview but the others (added from the program) do not appear either.
Your textview (R.id.textview) has a width of match_parent, effectively pushing your other views (the linearlayout) off screen. Instead you can give it a width of wrap_content and possibly a layout_weight of 1.
I Have activity that get some data from the internet, and shows it to the screen.
I'm using scroll view cause it's long text, I also want different text style for a different data,so I use few textViews with a different style and to show it on the Activity screen,
my problem is that scroll view can handle only one view, so how can I use scrolling to show different style of Text view, I tried to add LinearLayout to the scrollView and add all the textViews dynamically in code to this LinearLayout ,but I'm getting exception - scroll view can host only one direct child.
The code below:
/** this is the function, which called from the onClick method.
wanted data object contains 2 strings title message and the message itself.
When debug the code i can see that there's two String values in each loop.
but i cant add the linearLayout to my scrollView - exception ScrollView can host only one direct child */
private void showResult(ArrayList<WantedData> result) {
// TODO Auto-generated method stub
TextView title;
TextView data;
scrollLayout = (LinearLayout) findViewById(R.id.LlScrollView);
for (WantedData curr : result) {
if (curr.getTitle() == null) {
break;
}
title = new TextView(this);
title.setText(curr.getTitle());
scrollLayout.addView(title, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
data = new TextView(this);
data.setText(curr.getData());
scrollLayout.addView(data, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
}
scroll.addView(scrollLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
//at the onCreate method - scroll = (ScrollView) findViewById(R.id.SvShowTextFromServer);
}
the xml file:
<?xml version="1.0" encoding="utf-8"?>

The problem is double creating of container in ScrollView. You should not create it in activity, but take already defined from xml:
LinearLayout scrollContainer = (LinearLayout)findViewById(R.id.LlScrollView);
for (...) {
//create here some text
scrollLayout.addView(text);
}
If you have defined a LinearLayout in XML you don't have to create a new LinearLayout in your code but you have to retrieve the existing one in this way
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.LlScrollView);
Otherwise you have to remove the LinearLayout in your XML and add all by code.
