Stop android scrollview prevent parent LinearLayout onclick

Stop android scrollview prevent parent LinearLayout onclick - java

I need to allow user to CLICK anywhere on the screen, so I've implemented onClick listener for mainLayout and it worked great.
But the problem is I've got to add a scrollview inside mainLayout to support small screen sizes and after adding scrollview, it blocks the parentLayout (in my case mainLayout) CLICK EVENT.
Just to exaplin this, a sample layout is as follows.
<!-- MAIN LAYOUT WHERE I NEED
THE CLICK EVENT-->
<LinearLayout
android:id="#+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#bebebe"
android:orientation="vertical"
android:onClick="onClick_MainLayout">
<ScrollView
android:id="#+id/mainScrollView"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="#+id/button1"
android:layout_width="100dp"
android:layout_height="40dp"
android:text="TEST BUTTON 1"
android:onClick="onClick_Button1"/>
<Button
android:id="#+id/button2"
android:layout_width="100dp"
android:layout_height="40dp"
android:text="TEST BUTTON 2"
android:onClick="onClick_Button2"/>
<TextView
android:id="#+id/textview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Text View"/>
</LinearLayout>
</ScrollView>
</LinearLayout>
I searched for this and found various ideas like disableing onClick manually in all other views inside scrollview etc but non of them works.
NOTE: I tried both implementing onClick listener manually in java and adding android:onClick="onClick_MainLayout" in to layout. Both the same.
EDITS ----------------------
All the changes I've done as you (#IntelliJ Amiya) mentioned is as below. Please let me know anything is missing.
<RelativeLayout
android:id="#+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#bebebe">
<ScrollView
android:id="#+id/mainScrollView"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/button1"
android:layout_width="100dp"
android:layout_height="40dp"
android:text="TEST BUTTON 1"/>
<Button
android:id="#+id/button2"
android:layout_below="#+id/button1"
android:layout_width="100dp"
android:layout_height="40dp"
android:text="TEST BUTTON 2"/>
<TextView
android:id="#+id/textview1"
android:layout_below="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Text View"/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
And in on create
findViewById(R.id.mainLayout).setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Log.v("MyLogs", "Click Event Fires...");
}
});

Your Scroll view overlaps the linear layout i.e #mainLayout,so
set its height to wrap content
then you can perform onclick for both scroll view buttons and mainlayout.
Pls tell me if i wrong.

android:id="#+id/mainScrollView"
android:layout_width="match_parent"
android:layout_height="wrap_content">

I set onclick on FrameLayout and LinearLayout, i wanna show log is status but when i touch it, nothing happen.
And then, i set android:layout_width="1dp", android:layout_height="1dp" of id: status_bar_all_contents, it show log: status, but status_bar_all_contents will gone, so i dont want that.
So how to fix when i touch it and show log status?
Ps: Sorry for my english is not good.

Layouts typically pass-through clicks to their children.
You can try this solution here disabling all children onclicks and enabling the FrameLaoyuts onclicks. But I don't think that will work with the LinearLayout on top of that.
Android frame layout click listener not working
My advice wrap the entire view in a ConstraintLayout, and position 2 basic <View>s
One <View> that is constrained to match the FrameLayout
One <View> that is constrained to match the LinearLayout
These <View>s will act as overlays.
<View
android:id="#+id/status_bar_overlay"
app:layout_constraintEnd_toEndOf="#id/status_bar"
app:layout_constraintStart_toStartOf="#id/status_bar"
app:layout_constraintTop_toTopOf="#id/status_bar"
app:layout_constraintBottom_toBottomOf="#id/status_bar" />
<View
android:id="#+id/status_bar_all_contents_overlay"
app:layout_constraintEnd_toEndOf="#id/status_bar_all_contents"
app:layout_constraintStart_toStartOf="#id/status_bar_all_contents"
app:layout_constraintTop_toTopOf="#id/status_bar_all_contents"
app:layout_constraintBottom_toBottomOf="#id/status_bar_all_contents" />
Set the two View's onClickListener in the Activity and there you go.

setOnItemClickListener() not working on ExpandableHeightGridView in Fragment

Hello good morning in my view i cant handled the setOnItemClickListener
I am trying to create an application which dynamically lists installed applications in a gridview.I am able to display the applications in a gridview form but not able to make these items clickable. Nothing happens when i click these items. The code inside the setOnItemClickListener does not get triggered on click event.

I think you can Change your Code
from
button.setOnItemClickListener(this);
To
button.setOnClickListener(this);
for example :-
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = findViewById(R.id.button);
button.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.button:
//Do Something
break;
}
}
}

Avoid clicking of full layout

I only want my textview with id clickable_txtView to be clickable in relative layout. Here is the code -
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#android:id/empty"
android:clickable="false">
<ImageView
android:layout_width="120sp"
android:layout_height="130sp"
android:layout_centerHorizontal="true"
android:src="#drawable/flower"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingTop="120sp"
android:text="Dont click me />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/clickable_txtView"
android:gravity="center"
android:paddingTop="140sp"
android:clickable="true"
android:text="Click me" />
</RelativeLayout>
#OnClick(R.id.clickable_txtView)
public void txtViewClick() {
//Some event
}
Thr problem is I am able to click whole relative layout and some event happens after onclicking relative layout.
How do I avoid this and make it limited to text view only.

Your textview has an attribute android:paddingTop="140sp" which basically wraps over the entire relative layout, because of which you are having the problem with onClick behaviour.
Use this RelativeLayout structure (provide ID to the "don't click me" textview, and place the "clickable textview" below it.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/empty"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">
<ImageView
android:layout_width="120sp"
android:layout_height="130sp"
android:layout_centerHorizontal="true"
android:src="#mipmap/ic_launcher"
android:layout_alignParentTop="true"
/>
<TextView
android:id="#+id/do_not_click"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingTop="120sp"
android:enabled="false"
android:text="Dont click me" />
<TextView
android:id="#+id/clickable_txtView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:gravity="center"
android:layout_below="#id/do_not_click"
android:text="Click me" />
</RelativeLayout>

In your activity where you are inflating this view try this:
first initialize your textview
TextView textView = (TextView) findViewById(R.id.clickable_txtView);
then apply clickListner on it
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Do your work here
}
});

I'm not sure but you can try adding below line to your parent layout
android:touchscreenBlocksFocus="true"
like
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#android:id/empty"
android:touchscreenBlocksFocus="true">

how to get a layout on click of imageview?

Hello.. I have a layout in which I have ImageView and EditText view. I want to add a different layout on click of ImageView of arrow.
It should look like this after click event of ImageView. How can I get this??
Pleas help...

For perfect answer please add your xml file and java file source code.
Example
MainActivity.java
public class MainActivity extends Activity {
LinearLayout linear1,linear2;
ImageView imgArrow;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
linear1 = (LinearLayout) findViewById(R.id.linear1);
linear2 = (LinearLayout) findViewById(R.id.linear2);
imgArrow = (ImageView) findViewById(R.id.imgArrow);
linear1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(linear2.getVisibility() == View.GONE){
linear2.setVisibility(View.VISIBLE);
imgArrow.setImageResource(R.drawable.up);
}else{
linear2.setVisibility(View.GONE);
imgArrow.setImageResource(R.drawable.down);
}
}
});
}
}
activity_main.xml
<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" >
<LinearLayout
android:id="#+id/linear1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/btnClick"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/tv1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="0.5"
android:text="Additional Contact" />
<ImageView
android:id="#+id/imgArrow"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_weight="0.2"
android:src="#drawable/down" />
</LinearLayout>
<LinearLayout
android:id="#+id/linear2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:visibility="gone"
android:orientation="vertical" >
<TextView
android:id="#+id/txt1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="User Name here" />
<TextView
android:id="#+id/txt2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="Phone number here" />
<Button
android:id="#+id/btnone"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="Click Here" />
</LinearLayout>
</LinearLayout>
Here down and up is image file for arrow.
so put that both arrow file in drawable folder.

You could just set an OnClickListener to the ImageView, which contains the arrow. Then assign a method, which handles the click and produces your different layout

How to add a 'Click for more details' expandable field to AlertDialog in android

I have a AlertDialog that is shown when there is an error and it prints 'Error, could not be added/whatever", I also have the result of the exception that I'd like to parse but not shown to all users, only to those that want to click on 'details' and read the exception.
AlertDialog.Builder dialogo1 = new AlertDialog.Builder(activity);
dialogo1.setTitle("Error");
dialogo1.setMessage("Could not update movie: " + result);
dialogo1.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogo1, int id) {
activity.finish();
}
});
dialogo1.show();
There is my code, pretty simple, right? I haven't been able to find this answer anyway and I'm starting to think it is just not possible

what you want is a custom alert dialog.
so for that you will have to us a layout and define your dialog.Then initialize your listeners etc like it was a normal view that you are defining
dialog_layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:src="#drawable/header_logo"
android:layout_width="match_parent"
android:layout_height="64dp"
android:scaleType="center"
android:background="#FFFFBB33"
android:contentDescription="#string/app_name" />
<TextView
android:id="#+id/error"
andorid:text="Error Message"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/moreDetailsButton"
android:text="Click for more details"
android:inputType="textPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="#+id/moreDetailsView"
android:text="Click for more details"
android:inputType="textPassword"
android:layout_width="match_parent"
android:visibility="gone";
android:layout_height="wrap_content"/>
<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/moreDetailsButton"
/>
</RelativeLayout>
and in your class
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog_layout);
TextView error=(TextView)dialog.findViewById(R.id.error);
Button errorButton=(Button)dialog.findViewById(R.id.moreDetailsButton);
Button okButton=(Button)dialog.findViewById(R.id.ok);
//Do whatever you want with the rest of the dialog
// initialize all the onclick listeners a usual
errorButton.setOnClickListener(new View.onClickListener(){
#Override
public void onClick(View v){
TextView errorDetails=(TextView)dialog.findViewById(R.id.moreDetailsView);
errorDetails.setText(detailedErrorMessage) //add the details to this text view;
errorDetails.setVisibility(View.VISIBLE);
}
});
dialog.show();
Sorry if there are any syntactically errors if the ctrl+c,ctrl+v of this doesnt work.My IDE decided to misbehave today.
Follow this for details on a custom alert dialog.
