Create ImageButton after pushing on ImageButton

Create ImageButton after pushing on ImageButton - android

I have two rows of ImageButtons. Аfter clicking on any of the first row, I want the first row to be removed and the second row to appear, with the ImageButton centered. It should look something like this: "https://lifehacker.ru/special/travel-checklist/".
The layout of the first row:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#bbbbbb"
android:orientation="horizontal">
<ImageButton
android:id="#+id/winter"
android:layout_width="192dp"
android:layout_height="183dp"
android:layout_alignParentRight="true"
android:layout_gravity="center"
android:layout_weight="2"
android:gravity="left|center_vertical"
android:onClick="Winter"
android:paddingTop="32sp"
android:scaleType="fitCenter"
android:src="#drawable/snejinka"
android:text="Зима"
android:textColor="#FFFFFF" />
<ImageButton
android:id="#+id/Middle"
android:layout_width="192dp"
android:layout_height="183dp"
android:layout_alignParentRight="true"
android:layout_gravity="center"
android:layout_weight="2"
android:gravity="left|center_vertical"
android:onClick="Middle"
android:paddingTop="32sp"
android:scaleType="fitCenter"
android:src="#drawable/listok"
android:text="Весна/Осень"
android:textColor="#FFFFFF" />
<ImageButton
android:id="#+id/Summer"
android:layout_width="192dp"
android:layout_height="183dp"
android:layout_alignParentRight="true"
android:layout_gravity="center"
android:layout_weight="2"
android:gravity="left|center_vertical"
android:onClick="Summer"
android:paddingTop="32sp"
android:scaleType="fitCenter"
android:src="#drawable/unnamed"
android:text="Лето"
android:textColor="#FFFFFF" />
</LinearLayout>
The layout of the second row:
<ImageButton
android:id="#+id/three"
android:layout_width="192dp"
android:layout_height="183dp"
android:layout_alignParentRight="true"
android:layout_weight="2"
android:gravity="left|center_vertical"
android:onClick="three"
android:paddingTop="32sp"
android:scaleType="fitCenter"
android:src="#drawable/three"
android:text="three"
android:textColor="#FFFFFF" />
<ImageButton
android:id="#+id/seven"
android:layout_width="192dp"
android:layout_height="183dp"
android:layout_alignParentRight="true"
android:layout_weight="2"
android:gravity="left|center_vertical"
android:onClick="seven"
android:paddingTop="32sp"
android:scaleType="fitCenter"
android:src="#drawable/seven"
android:text="three"
android:textColor="#FFFFFF" />
<ImageButton
android:id="#+id/fourteen"
android:layout_width="192dp"
android:layout_height="183dp"
android:layout_alignParentRight="true"
android:layout_weight="2"
android:gravity="left|center_vertical"
android:onClick="fourteen"
android:paddingTop="32sp"
android:scaleType="fitCenter"
android:src="#drawable/fourteen"
android:text="three"
android:textColor="#FFFFFF" />
And here is my activity for both rows. I dont know, how to make the second row appear after the first clicked (the second row is under comments)

You can play visibility in your Linear Layout which has multiple ImageButton after you click on several ImageButton items in line one.
You can try this code.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center"
tools:context=".MainActivity">
<LinearLayout
android:id="#+id/layoutRowOne"
android:orientation="horizontal"
android:background="#android:color/holo_blue_light"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:text="YES"
android:id="#+id/btnLayoutOneYes"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<Button
android:text="NO"
android:id="#+id/btnLayoutOneNo"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
<LinearLayout
android:id="#+id/layoutRowTwo"
android:orientation="horizontal"
android:visibility="gone"
android:background="#android:color/holo_orange_light"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:text="HOT"
android:id="#+id/btnLayoutTwoHot"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<Button
android:text="COLD"
android:id="#+id/btnLayoutTwoCold"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</LinearLayout>
MainActivity
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import kotlinx.android.synthetic.main.activity_main.*
class MainActivity : AppCompatActivity() {
private var statusRowOne = false
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
btnLayoutOneYes.setOnClickListener {
statusRowOne = true
if (statusRowOne) {
layoutRowOne.visibility = View.GONE
layoutRowTwo.visibility = View.VISIBLE
}
}
btnLayoutOneNo.setOnClickListener {
statusRowOne = true
if (statusRowOne) {
layoutRowOne.visibility = View.GONE
layoutRowTwo.visibility = View.VISIBLE
}
}
}
}
I hope this code can help your case.

You can use Linear layout and frame layout to separate each and show the image buttons based on click event.

How to add and remove CardView from LinearLayout on button click in android studio?

I have a linear layout that contains a cardView. I want to add and delete cardViews dynamically on button clicks. I have tried the following code but the delete button doesn't work moreover the padding of dynamically added view changes on its own after adding a new as shown in picture below.

The parameter v in onDelete(View v) is not the CardView that you want to be removed. It's the ImageView that you click.
In onAddField() do this:
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.experience_details_row, null);
ImageView delRowBtn = rowView.findViewById(R.id.delRowBtn);
delRowBtn.setTag(rowView);
parentRelativeLayout.addView(rowView, parentRelativeLayout.getChildCount());
what the above code does is store the new CardView object in delRowBtn's tag. Also I removed -1 from parentRelativeLayout.getChildCount() to add the new CardView at the end.
But the above logic must be applied also to the 1st CardView that is already there, so in onCreate() add this:
CardView experienceInfoActivityFormCardVw = findViewById(R.id.experienceInfoActivityFormCardVw);
ImageView delRowBtn = findViewById(R.id.delRowBtn);
delRowBtn.setTag(experienceInfoActivityFormCardVw);
In onDelete() do this:
CardView cv = (CardView) ((ImageView) v).getTag();
parentRelativeLayout.removeView(cv);
what the above code does is retrieves the CardView object from delRowBtn's tag and removes it from parentRelativeLayout.

Avd showing old version of my application

So i've make some change's in my app (it was about nesting layouts - My root layout, was linear layout,i wanted to change it to relative layout,i remember,it was something wrong with lines like xlmns:tools etc. I've copy those lines from my previous app,but then i've got an error that something is missing,so i google it,and somebody wrote about delete .idea and .gradle folders so i did,and now,my avd showing me "old content" just app before some changes. How i can solve it? The application that i've trying to make,it's just an typical clicker at case of my course. It's about to counting score of two teams.

Just Clean and rebuild your project and then uninstall app from device and then run again in device it will works fine (If you really make changes in code)

An alert dialog with an image will appear once LinearLayout is clicked

here is my full code as you requested #mobie.. the Symptoms.java and the question.xml..dont matter the other code..just on the alert dialog that i asked.

Create Layout Like Below for Dialog Box : dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp" />
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_toRightOf="#+id/image"/>
<Button
android:id="#+id/dialogButtonOK"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Ok "
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_below="#+id/image"
/>
</RelativeLayout>
Then, Where you want to place the Alert, Do like below
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog);
dialog.setTitle("Your Title");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Text");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

If you have set src attribute in xml, then to update UI use setImageResource()
If you have set background attribute in xml then to update UI use setImageDrawable()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//First set content view..
setContentView(R.layout.activity_progress);
b1 = (ImageView) findViewById(R.id.b1);
b2 = (ImageView) findViewById(R.id.b2);
b3 = (ImageView) findViewById(R.id.b3);
resetall = (ImageView) findViewById(R.id.reset_all);
undo = (ImageView) findViewById(R.id.undo);
Header header =(Header)findViewById(R.id.header);

If Your onClickListener works correct, in Your case You have to change the source not background, for example:
b2.setImageResource(R.drawable.yourImage);

How to place 2 buttons at the same position in my layout

I have My Table row like below in my xml layout:
<TableRow
android:layout_marginTop="10dp"
>
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="256dp"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/titlename"
android:layout_="#+id/playbtn"
android:layout_marginTop="4dp"
/>
<Button
android:id="#+id/playbtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:background="#drawable/play"
android:layout_marginBottom="3dp"/>
<Button
android:id="#+id/pausebtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_toTopOf="#+id/playbtn"
android:layout_alignParentBottom="true"
android:background="#drawable/pause"
android:layout_marginBottom="3dp"/>
</TableRow>
and my output is as below,
my requirement is to show play pause buttons at the same position in my layout?
Could any one help?

Use FrameLayout and put one button over another
Like this
<FrameLayout ... >
<Button
android:id="#+id/playbtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/play"/>
<Button
android:id="#+id/pausebtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/pause"/>
</FrameLayout>
This will put Pause button over Play Button. Make the necessary button visible and invisible according to your need

Try using this layout. Use combination of LinearLayout and FrameLayout to achieve the desired result.
<TableRow
android:layout_marginTop="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weight="1"
android:layout_alignLeft="#+id/titlename"
android:layout_="#+id/playbtn"
android:layout_marginTop="4dp"
/>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<Button
android:id="#+id/playbtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/play"/>
<Button
android:id="#+id/pausebtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/pause"/>
</FrameLayout>
</LinearLayout>
</TableRow>

once Try this:
<TableRow
android:id="#+id/tableRow1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".8" />
<Button
android:id="#+id/play"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".2"
/>
</TableRow>
Main Activity
private boolean playing = false;
Button play;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play=(Button) findViewById(R.id.play);
play.setBackgroundResource(R.drawable.pause);
play.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if(playing){
playing = false;
play.setBackgroundResource(R.drawable.pause);
}
else {
playing = true;
play.setBackgroundResource(R.drawable.play);
}
}
});
}

Why can't you try merge?
Have a glance of this.
http://android-developers.blogspot.in/2009/03/android-layout-tricks-3-optimize-by.html

You don't need to create two buttons for it. You can do it with single. I have created a sample program. I find this to be a cleaner approach.
Layout for MainActivity
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<Button
android:id="#+id/buttonPlayPause"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Here is MainActivity
package in.live.homam.imagebuttonexample;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
private Button buttonPlayPause;
private static final int resourceIdPlay = R.drawable.play;
private static final int resourceIdPause = R.drawable.pause;
private int resourceIdButton = resourceIdPlay;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonPlayPause = (Button) findViewById(R.id.buttonPlayPause);
buttonPlayPause.setBackgroundResource(resourceIdButton);
buttonPlayPause.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(resourceIdButton == resourceIdPlay) {
resourceIdButton = resourceIdPause;
Log.d("Tag", "Playing");
}
else {
resourceIdButton = resourceIdPlay;
Log.d("Tag", "Paused");
}
buttonPlayPause.setBackgroundResource(resourceIdButton);
}
});
}
}
