how to create 2 column layout with merging column? - android

how to create this kind of layout in android
i have tried using table layout. but getting error in creating this.
please check my code i am able to display images. 1 image in 1 row. but i want 2 small images in 1 row. and continues.
here is my code
private void getBannerList() {
final Call<BannerList_Model> itemMainResponse = APIHandler.getApiService().bannerList(getFiledMapForItemList());
itemMainResponse.enqueue(new Callback<BannerList_Model>() {
#Override
public void onResponse(Response<BannerList_Model> response, Retrofit retrofit) {
BannerList_Model itemResponse = null;
itemResponse = response.body();
if (itemResponse == null) {
UIUtils.showToast(getContext(), "Server Error !");
} else {
String msg = itemResponse.getMsg().toString();
if (msg.equals("success")) {
userList = itemResponse.getBannerList();
if(userList != null) {
TableLayout table = (TableLayout) view.findViewById(R.id.tblBanner_list);
table.setColumnStretchable(0,true);
table.setColumnStretchable(1,true);
int tsize = userList.size();
TextView[] t1 = new TextView[tsize];
ImageView[] img = new ImageView[tsize];
for(int i=0; i<userList.size();i++)
{
TableRow row = new TableRow(getContext());
String banner_size = userList.get(i).getBannerSize().toString();
img[i] = new ImageView(getContext());
Picasso.with(getContext())
.load(Constants.VIDEO_URL + userList.get(i).getBannerUrl())
.into(img[i]);
row.addView(img[i]);
table.addView(row);
}
}
}
}
}
}
});
}
here is the video how i want layout
http://shrivivah.com/layout.mp4
if there is 2 small images than it will display in 1 row.
if there is 2 medium or full size image than it will display in 1 row each.
if 1 small and 2 medum than 1 image per row to display.
layout image

Your mistake is that you are adding TextView to TableRow(row) but you didn't add row to TableLayout. Here is an example for what you need. You can set some margins and add button.

Items are not scrolling.
how to solve this. please help.
thanks in advance.

Then you need to change itemView's xml file ,
android:layout_height="match_parent"
instead of like ,
android:layout_height="wrap_content"

Simple change in spirometer_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
....Your design code
</LinearLayout>

I was having problem with the same from such a long time. Then I found a solution that worked for me.
Add a ListViewHelper java class. Here below is code for ListViewHelper.java
package com.molescope;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListAdapter;
import android.widget.ListView;
public class ListViewHelper {
public static void getListViewSize(ListView listView){
ListAdapter adapter = listView.getAdapter();
if(adapter!=null){
int totalHeight = 0;
//setting list adapter in loop tp get final size
for (int i=0; i<adapter.getCount(); i++){
View listItem = adapter.getView(i, null, listView);
listItem.measure(0,0);
totalHeight += listItem.getMeasuredHeight();
}
//setting listview items in adapter
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() *
(adapter.getCount()-1));
listView.setLayoutParams(params);
}else{
return;
}
}
}
And after adding this java file, in your code wherever you are setting adapter to listview, right after that line add the code below:
ListView myList=(ListView) findViewById(R.id.listView);
myList.setAdapter(new ArrayAdapter<String>.
(this,android.R.layout.simple_list_item_1, listview_array));
ListViewHelper.getListViewSize(myList);

Use this code if you have a fixed size of elements.

Use compile 'com.android.support:cardview-v7:25.0.0' to get the CardView.
this is the sample output.

use ListView or RecyclerView with your custom list item which will contain image buttons and custom adapter

Instead of px use dp it´s much better!
If you want a fixed list, your XML is correct, but if you want a dynamic list, you should use ListView or RecycleView , as the others users said.
The weight in your LinearLayout is wrong, weight should be used when you desires your screen to fit in every screen, no matter the size ( and you will need to "distribute" your weigth throught the children´s).
To make your screen similar to the first image, you need to set a background in your second LinearLayout

Okey this a recyclerview for what you want,
public class MainPageAdapter extends RecyclerView.Adapter<MainPageAdapter.ViewHolder> {
private #DrawableRes int[] iconDrawables;
private String[] texts;
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
final View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.img_lockIcon.setImageResource(iconDrawables[position]);
holder.txt_whatever.setText(texts[position]);
}
#Override
public int getItemCount() {
return iconDrawables != null ? iconDrawables.length : 0;
}
public void setData(#DrawableRes int[] iconDrawables, String[] texts){
this.iconDrawables = iconDrawables;
this.texts = texts;
this.notifyDataSetChanged();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
ImageView img_icon;
TextView txt_whatever;
ImageView img_lockIcon;
public ViewHolder(View itemView) {
super(itemView);
img_icon = itemView.findViewById(R.id.item_img_icon);
txt_whatever = itemView.findViewById(R.id.item_txt_whatever);
img_lockIcon = itemView.findViewById(R.id.item_img_lockIcon);
}
}
}
this is R.layout.item,

setContentView(R.layout.activity_main);
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
MainPageAdapter adapter = new MainPageAdapter();
recyclerView.setAdapter(adapter);
//Set your data
//adapter.setData();
}
}
You can change color as you want and also notify that ı used two different arrays for adapter but you can use pojo classes also. Hope this helps you.

Reverse layouts inside RelativeLayout programmatically

I have one relativeLayout and three view's inside RelativeLayout. There views are place on each other.
<RelativeLayout
android:id="#+id/includelayoutgroup"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/transparentColorView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/keyboard_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="visible">
<include
layout="#layout/transfer_keyboard_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/finalRequestView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible">
<include
layout="#layout/fragment_transfer_new_version_container_child"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
</RelativeLayout>
Is it a possible to reverse position my view's? I mean,in my code last Layout is finalRequestView and in button click i would to my last view in first position,and other view's place on my view,
How i can solve this problem?

I try to reverse layout by following demo & it works as you want, please take a look
ReverseLayout.java
public class ReverseLayout extends AppCompatActivity {
LinearLayout llRoot;
Button btReverseLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reverse_layout);
llRoot = (LinearLayout) findViewById(R.id.llRoot);
btReverseLayout = (Button) findViewById(R.id.btReverseLayout);
btReverseLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<View> alViews = new ArrayList<View>();
for (int i = llRoot.getChildCount() - 1; i >= 0; i--) {
View view = llRoot.getChildAt(i);
llRoot.removeViewAt(i);
alViews.add(view);
}
for (int j = 0; j < alViews.size(); j++) {
llRoot.addView(alViews.get(j));
}
}
});
}
}

How to avoid ListView put rows with TextView transparent

I'm developing a Chat App, so I create a list of friends.
Take a look at my ListView declaration at layout.xml
<ListView
android:listSelector="#android:color/transparent"
android:id="#+id/usersList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:background="#android:color/transparent"
android:cacheColorHint="#android:color/transparent"
android:divider="#android:color/transparent"
android:dividerPadding="2dp"
android:overScrollFooter="#null"
android:scrollingCache="false"
android:transcriptMode="normal"
/>
And the behavior of this ListView is annoying.
When I run my app in a phone with Android 2.3 the TextView itens of my ListView becomes transparent just like the image below:
Sometimes when a press the itens the color of TextView back to normality.
When I run my app in a phone with Android 4.1 this problem not happens.
My user item xml:
<?xml version="1.0" encoding="utf-8"?>

How to avoid this problem?

There is a chance that the TextViews are not showing at all. not the colour is changing. you can check that by setting a background for the textviews.
A few mistakes in the item xml I would like to point out:
You have two items in the horizontal layout. the linear layout that contains the image and the linear layout that contains textview. In this case you can't have them both match_parent. the total size would be screen size * 2.
when setting weight for a linear layout in a horizontal container you set the width to 0dp.
your weight sum is 1 + 0.5 = 1.5. means that the image will reserve 2/3 of screen size and textview 1/3. looks un-logical.
These un logical values could cause different layout display for different os version.
Solution:
<?xml version="1.0" encoding="utf-8"?>

android:textSize="12sp" />
At my LinearLayout which has the TextViews at my user_item.xml(The layout of itens of the List). I put background color as White. Its strange because the main ViewGroup of this layout is already set with background color White. Now My itens appears normally.

u can make it without using expandable list-view..u have to just control visibility of your views.
