I have this layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#color/white"
android:orientation="vertical">
<TextView
android:id="#+id/txt_daytime"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fontFamily="sans-serif-medium"
android:text="-"
android:textColor="#color/gray"
android:textSize="16sp" />
<TextView
android:id="#+id/txt_temp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fontFamily="sans-serif-medium"
android:text="-"
android:textColor="#color/black"
android:textSize="18sp" />
</LinearLayout>
I want to add it to my linear layout in main layout:
<LinearLayout
android:id="#+id/temp_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_marginStart="20dp"
android:layout_marginEnd="20dp"
android:orientation="horizontal">
in code. I'm using this:
val dayTime = listOf(DayTime.NIGHT, DayTime.MORNING, DayTime.DAY, DayTime.EVENING)
val tempContainer = binding.tempContainer
for (temp in dayTime) {
val weather = weatherData.getWeather(temp)
val view = LayoutInflater.from(requireContext()).inflate(R.layout.temp_layout, tempContainer) as LinearLayout
view.apply {
layoutParams = (layoutParams as LinearLayout.LayoutParams).apply {
weight = 1f
}
}
but how can i set values to those two TextViews in my reusing layout in code?
When i'm trying to get children in this view i can't choose TextView and also i can't set values to this children
((TextView) view.findViewById(R.id.txt_daytime)).setText("Custom1");
you can use this below code also
LayoutParams lparams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
TextView tv=new TextView(this);
tv.setLayoutParams(lparams);
tv.setText("test");
this.m_vwJokeLayout.addView(tv);
It's very simple to assign a value on text view.
1 ) you need to initialize textview like this:
val textView = findViewById(R.id.text_view_id) as TextView
2 ) set a text like this
textView.text = "Your text that you want to set"

I am designing a Feed in which I want the posts in the form of a Card which I implemented using design library of Google. I have created my layout but as the posts will be fetched dynamically therefore I wanted to dynamically create my layout in Kotlin. For that I created a function which will take Image,Title,Description as the parameters and will return a Card View Object.
To set the attributes in CardView I tried layoutParams but using it just crashed my app
val cardViewParam = cardView.layoutParams as CoordinatorLayout.LayoutParams
In this code I tried every layout type Linear,Relative,Coordinator and even ViewGroup but my app keeps on crashing every time.
This is my layout:

I tried this code to create layout dynamically:
(NOTE: This code was made just to create basic Card excluding the Rating Bar and other Action Buttons)
fun createAdsPost(view: View, photo: ImageView, titleText: String, descText: String): CardView {
val cardView = CardView(view.context)
val cardViewParam = cardView.layoutParams as CoordinatorLayout.LayoutParams
cardView.layoutParams = cardViewParam
cardViewParam.width = LinearLayout.LayoutParams.MATCH_PARENT
cardViewParam.height = LinearLayout.LayoutParams.WRAP_CONTENT
cardViewParam.setMargins(dpToPx(5, view), dpToPx(5, view), dpToPx(5, view), dpToPx(5, view))
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
cardView.elevation = dpToPx(50, view).toFloat()
}
cardView.apply {
radius = dpToPx(10, view).toFloat()
this.layoutParams = cardViewParam
}
val linear1 = LinearLayout(view.context)
linear1.orientation = LinearLayout.VERTICAL
linear1.setPadding(dpToPx(10, view), dpToPx(10, view), dpToPx(10, view), dpToPx(10, view))
linear1.clipToPadding = false
val linear1Param = linear1.layoutParams as LinearLayout.LayoutParams
linear1Param.width = LinearLayout.LayoutParams.MATCH_PARENT
linear1Param.height = LinearLayout.LayoutParams.WRAP_CONTENT
linear1.layoutParams = linear1Param
photo.scaleType = ImageView.ScaleType.CENTER_CROP
photo.adjustViewBounds = true
val photoParams = photo.layoutParams as LinearLayout.LayoutParams
photoParams.apply {
width = LinearLayout.LayoutParams.MATCH_PARENT
height = dpToPx(180, view)
topMargin = dpToPx(-10, view)
bottomMargin = dpToPx(-10, view)
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
photoParams.marginStart = dpToPx(-10, view)
photoParams.marginEnd = dpToPx(-10, view)
}
linear1.addView(photo)
val title = TextView(view.context)
title.apply {
ellipsize = TextUtils.TruncateAt.END
maxLines = 1
text = titleText
}
val titleTextParams = title.layoutParams as LinearLayout.LayoutParams
titleTextParams.apply {
width = LinearLayout.LayoutParams.MATCH_PARENT
height = LinearLayout.LayoutParams.WRAP_CONTENT
topMargin = dpToPx(16, view)
}
linear1.addView(title)
val desc = TextView(view.context)
desc.apply {
ellipsize = TextUtils.TruncateAt.END
maxLines = 2
text = descText
setTextColor(Color.parseColor("#626567"))
}
val descTextParams = desc.layoutParams as LinearLayout.LayoutParams
descTextParams.apply {
width = LinearLayout.LayoutParams.MATCH_PARENT
height = LinearLayout.LayoutParams.WRAP_CONTENT
topMargin = dpToPx(8, view)
}
linear1.addView(desc)
cardView.addView(linear1)
return cardView
}
When I am using these codes my app is crashing. I tried to debug my codes and came to know that the first error is in the layoutParams of CardView.
In short, I want to know how can I set attributes in the Card View
Also, Please Tell is this the only way to create dynamic layout or there is a more efficient way. I am new in Android Developing.
I would like to suggest one thing, if your requirement is to create view dynamically then you just try one thing that is :
1) Make a separate layout file for your dymanic view
2) Inflate that layout using :
val layoutInflater = getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
layoutInflater!!.inflate(R.layout.your_layout_file)
3) Now you will have view, then you just have to access the layour views using something like :
view.findViewById(you view id)
4) now you will be able to create and access your view dynamically easily
Note:
getContent() : will come according to your usage on fragment or in activity, so need to change it accordingly
same as inflate method, use parameter according to your requirement
You are casting the LayoutParams as CoordinatorLayout.LayoutParams whereas you are creating a view dynamically that doesn't have a parent view, and that's I think is the issue.
If you are creating the view dynamically than you should create new LayoutParams as well, according to its parent container.
For e.g., if you want to add CardView in a LinearLayout than, the LayoutParams should be as below:
val cardView = CardView(view.context)
val cardViewParams = LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT).also {
it.setMargins(dpToPx(5, view), dpToPx(5, view), dpToPx(5, view), dpToPx(5, view))
}
cardView.apply {
radius = dpToPx(10, view).toFloat()
this.layoutParams = cardViewParam
}
...
...
val linear1 = LinearLayout(view.context)
val linear1Param = FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT)
...
...
cardView.addView(linear1)
For linear1, we have taken FrameLayout.LayoutParams as in our case we are going to add it as a child of CardView, which is an extended FrameLayout.
I have two layouts, i inflate one layout into another and want to display this inflated layout including textview as many times as condition is true . I set the textview value as value of i and also set the layout top margin. but it displaying value of i in one row only and rest are blank,also its setMargin() also not working.Below is what i have done yet.
public void displayRows(){
int n= 6;
for(int i=0;i< n;i++){
LinearLayout container = (LinearLayout)findViewById(R.id.layoutContainer);
View hiddenInfo = getLayoutInflater().inflate(R.layout.dynamic, container, false);
container.addView(hiddenInfo);
LinearLayout hiddenLayout = (LinearLayout)findViewById(R.id.dynamic);
TextView textView = (TextView) findViewById(R.id.text);
textView.setText("Text"+i);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(0, 30, 0, 0);
hiddenLayout.setLayoutParams(layoutParams);
hiddenLayout.addView(textView);
}

I also want to know how to remove all the generated dynamic rows on click remove button.
Replace
LinearLayout hiddenLayout = (LinearLayout)findViewById(R.id.dynamic);
TextView textView = (TextView) findViewById(R.id.text);
with
LinearLayout hiddenLayout = (LinearLayout) hiddenInfo.findViewById(R.id.dynamic);
TextView textView = (TextView) hiddenInfo.findViewById(R.id.text);
And remove this line
hiddenLayout.addView(textView);
I am currently working at developing an app that requires a dynamically generated GridView. In the layout added to the GridView through an adapter I have a LinearLayout that takes information from an ArrayList and then it should display an ImageView followed by a TextView. I have done that programmatically, but some random space appears between the two of them.
I have tried removing the padding, removing the margin, setting the adjustViewBounds of the image to true and also removing the inner padding of the TextView and none of these things work.
Here is the .xml file containing the LinearLayout to be populated:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#drawable/rounded_text_black">
<ImageView
android:id="#+id/separator"
android:layout_width="match_parent"
android:layout_height="2dp"
android:scaleType="fitXY"
android:src="#drawable/horizontal_white_line"
android:layout_centerVertical="true"/>
<LinearLayout
**android:id="#+id/orderLayout"**
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignBottom="#id/separator"
android:orientation="vertical"
android:paddingTop="40dp">
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignTop="#id/separator"
android:orientation="vertical"
android:layout_gravity="center"
android:layout_marginTop="10dp">
<ImageView
android:layout_width="15dp"
android:layout_height="15dp"
android:scaleType="fitXY"
android:src="#mipmap/effects"
android:layout_gravity="center"/>
<TextView
android:id="#+id/moodText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
style="#style/smallText"
android:padding="0dp"/>
<TextView
android:id="#+id/tastesText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
style="#style/smallText"
android:textAllCaps="false"
android:padding="0dp"/>
<TextView
android:id="#+id/tastesText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
style="#style/smallText"
android:textAllCaps="false"
android:padding="0dp"/>
</LinearLayout>
</RelativeLayout>
Here is the code that generates the image-text pairs:
for(int i = 0; i < 3; i++){
int currentPos = orderSize - i;
if(currentPos >= 0){
LinearLayout container = new LinearLayout(v.getContext());
LinearLayout.LayoutParams containerParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
container.setOrientation(LinearLayout.HORIZONTAL);
container.setGravity(Gravity.RIGHT);
container.setLayoutParams(containerParams);
ImageView img = new ImageView(v.getContext());
LinearLayout.LayoutParams imgParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.MATCH_PARENT);
imgParams.gravity=Gravity.RIGHT;
img.setLayoutParams(imgParams);
img.setPadding(0,0,0,0);
if(order.get(currentPos).delivered){
img.setImageResource(R.drawable.green_circle);
}
else{
img.setImageResource(R.drawable.yellow_circle);
}
TextView txt = new TextView(v.getContext());
txt.setTextColor(Color.WHITE);
txt.setText(order.get(currentPos).orderItem);
txt.setPadding(0,0,0,0);
container.addView(img);
container.addView(txt);
ll.addView(container);
}
And here is the result:
The red rectangle indicates the extra space.
Thank you very much.
I suggest you to create your line item view (green ball and drink name) in an xml layout, checking that all is working fine on a single line.
Then you can change your for cycle as follows:
for(int i = 0; i < 3; i++){
int currentPos = orderSize - i;
if(currentPos >= 0){
// inflate a new instance of view starting from an xml file
View tableLineView = getLayoutInflater().inflate(R.layout.table_line, null);
// Image view
ImageView iv = (ImageView)tableLineView.findViewById(R.id.ball);
if(order.get(currentPos).delivered){
iv.setImageResource(R.drawable.green_circle);
} else{
iv.setImageResource(R.drawable.yellow_circle);
}
// TextView
TextView tv = (TextView)tableLineView.findViewById(R.id.textview);
tv.setText(order.get(currentPos).orderItem);
// add to LinearLayout
ll.addView(tableLineView);
}
}
I can't test it now, if you find problems ask me.
Here you can read a discussion about view inflating
TextView txt = new TextView(this);
LinearLayout.LayoutParams txtParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.MATCH_PARENT);
txt.setLayoutParams(txtParams);
txt.setTextColor(Color.BLACK);
txt.setText("Hello World");
txt.setPadding(0,0,0,0);
Use this and you wont see padding anymore!!
I have a little bit problem that displaying list data to TextView in Android. My scenario is I have a TableLayout with Default One TableRow. Inside table row, I has been created new LinearLayout. Then, Four TextView created inside LinearLayout. I adding some default value to this textview. My default value is
1, 2014-02-05, S02, 20
Here my code snippet for above scenari0.
<TableLayout
android:layout_width="fill_parent"

Actually, I want to create dynamically TableRow, LinearLayout and TextView. Then, I put the list result to add these. The list result come from sqlite db. But, I can't get what I want. Here my code for looping the list and display the result. But, I got my some default value. Please pointing to me how can I get this. Thanks.
Here snippet for display list.
public void displayHistory(){
List<IspHistoryListObject> historyList = sqlaccess.getAllItems();
TableLayout showRow = (TableLayout) findViewById(R.id.history_table);
int count = 0;
for(IspHistoryListObject hl : historyList) {
count++;
TableRow tr = new TableRow(this);
LinearLayout ll = new LinearLayout(this);
ll.setLayoutParams(new LinearLayout.LayoutParams(50,30));
TextView tv_sync_no = new TextView(this);
TextView tv_sync_date = new TextView(this);
TextView tv_sync_orderid = new TextView(this);
TextView tv_sync_qty = new TextView(this);
tv_sync_no.setText(String.valueOf(count));
tv_sync_date.setText(hl.getSyncDate().substring(0,10));
tv_sync_orderid.setText(hl.getSyncOrderIdRef());
tv_sync_qty.setText(String.valueOf(hl.getQty()));
ll.addView(tv_sync_no);
ll.addView(tv_sync_date);
ll.addView(tv_sync_orderid);
ll.addView(tv_sync_qty);
tr.addView(ll);
showRow.addView(tr);
}
}
try this way here I gave sample or demo code you have to modify as per your requirement and still have problem let me know
main layout

super.onCreate(savedInstanceState);
setContentView(R.layout.table);

history_display_orderid.setText("S0"+(i+1));
history_display_quantity.setText(""+(20+(i+1)));
tableLayout.addView(tableRow);
}
}
}
check out context hierachy
for(IspHistoryListObject hl : historyList) {
count++;
TableRow tr = new TableRow(showRow.getContext());
LinearLayout ll = new LinearLayout(tr.getContext());
ll.setLayoutParams(new LinearLayout.LayoutParams(50,30));
TextView tv_sync_no = new TextView(ll.getContext());
TextView tv_sync_date = new TextView(ll.getContext());
TextView tv_sync_orderid = new TextView(ll.getContext());
TextView tv_sync_qty = new TextView(ll.getContext());
tv_sync_no.setText(String.valueOf(count));
tv_sync_date.setText(hl.getSyncDate().substring(0,10));
tv_sync_orderid.setText(hl.getSyncOrderIdRef());
tv_sync_qty.setText(String.valueOf(hl.getQty()));
ll.addView(tv_sync_no);
ll.addView(tv_sync_date);
ll.addView(tv_sync_orderid);
ll.addView(tv_sync_qty);
tr.addView(ll);
showRow.addView(tr);
}
With listview you can easily do this:
ActivityMain.java
ListView lst = (ListView) findViewById(R.id.listView);
View header = getLayoutInflater().inflate(R.layout.list_header, null);
lst.addHeaderView(header);
lst.setAdapter(new CustomerListAdapter(this,4));
list_header.xml is header layout
I developed one Simple app, which contains one textview.and my problem is that I want visible in invisible this text view on button click event.
At loadtime I do this
myTextView.setVisible(View.GONE);
and after this at Button Click event, I do this.
myTextView.setVisible(View.VISIBLE);
The textview is visible but it is overlap on below TextView means myTextView cannot contain space. So what can I do now?
use
myTextView.setVisible(View.INVISIBLE);
instead of
myTextView.setVisible(View.GONE);
to persist the space in layout.........
If you are using relativelayout, specify android:layout_below="id_of_above_text_view" in the second textview.
If you dont specify the relation to the views in relative layout, it will appear one above other
try this:
RelativeLayout layout = new RelativeLayout(this);
TextView tv1 = new TextView(this);
tv1.setText("A");
tv1.setId(1);
TextView tv2 = new TextView(this);
tv2.setText("B");
tv2.setId(2);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lp.addRule(RelativeLayout.BELOW, tv1.getId());
layout.addView(tv1);
layout.addView(tv2, lp);
and when you change visibility, call invalidate() on parent view of myTextView (layout here) or root view of your layout ( layout.getRootView() )
A slight change in your code should make it work fine I believe.
myTextView.setVisibility(View.INVISIBLE);
and after the button click,
myTextView.setVisibility(View.VISIBLE);
For doing it in the java code, have a go at this(haven't tried it out myself though)...
RelativeLayout rl = new RelativeLayout(this);
ImageView iv = new ImageView(this);
iv.setImageResource(R.drawable.xxx);
TextView txt = new TextView(this);
txt.setText("XXX");
rl.addView(iv,0);
rl.addView(txt,1);
This will show and hide the text(s) when the corresponding buttons are pressed.
Very useful if you want to control multiple text with buttons
