I have a button with an ImageView as overlay. The ImageView is not clickable so I can still use the button. Strangely the not clickable ImageView turns invisible when I touch the button and appears again when I release it.
<RelativeLayout
android:id="#+id/buttonMailLayout"
android:layout_width="208dp"
android:layout_height="160dp"
android:layout_centerHorizontal="true">
<Button
android:id="#+id/buttonMail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/metal"
android:text="Write Mail"
android:textSize="32dp"
android:gravity="bottom|center_horizontal"
android:paddingBottom="16dp"/>
<ImageView
android:id="#+id/imageMail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/email20"
android:elevation="2dp"
android:paddingTop="8dp"
android:paddingBottom="64dp"
android:clickable="false"/>
</RelativeLayout>
Here is the code I work with:
Button buttonMail = (Button) this.findViewById(R.id.buttonMail);
buttonMail.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), "New Mail to : " + p._email,
Toast.LENGTH_SHORT).show();
}
});
Any ideas what is going wrong? Could it have something to do with the elevation? I had to add 2dp elevation to my ImageView on 5.1 to get it in front of the button.
I think its the button default elevation behaviour in 5.0 and above versions causing this issue, try placing your button in separate layout this way and it should work:
<RelativeLayout
android:id="#+id/buttonMailLayout"
android:layout_width="208dp"
android:layout_height="160dp"
android:layout_centerHorizontal="true">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="bottom|center_horizontal"
>
<Button
android:id="#+id/buttonMail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/metal"
android:text="Write Mail"
android:textSize="32dp"
android:paddingBottom="16dp"/>
</FrameLayout>
<ImageView
android:id="#+id/imageMail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/email20"
android:elevation="2dp"
android:paddingTop="8dp"
android:paddingBottom="64dp"
android:clickable="false"/>
</RelativeLayout>

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;
}
}
}
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 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">
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
I need a TextView which scrolls automatically vertically. This is my layout code:
activity_info.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/iView"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerHorizontal="true"
android:contentDescription="#string/info"
android:src="#mipmap/infoImage" />
<TextView
android:id="#+id/tView"
android:layout_below="#+id/iView"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_centerHorizontal="true"
android:maxLines="500"
android:scrollbars="vertical" />
<RelativeLayout
android:layout_below="#+id/tView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center">
<Button
android:id="#+id/buttonYes"
android:layout_width="100dp"
android:layout_height="50dp"
android:text="YES" />
<Button
android:id="#+id/buttonNo"
android:layout_toEndOf="#id/buttonYes"
android:layout_width="100dp"
android:layout_height="50dp"
android:text="NO" />
</RelativeLayout>
</RelativeLayout>
I read that I have to input this line:
tView.setMovementMethod(new ScrollingMovementMethod())
into my onCreate method in my activity:
InfoActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info);
TextView tView = (TextView) findViewById(R.id.tView);
tView.setMovementMethod(new ScrollingMovementMethod());
}
If I do that, the TextView does not scroll automatically, if some new input (text) is inserted into the View. I know there are some other questions concerning the problem. But I've tried most of them.
How can I solve this problem?
Try to set the textView to android:gravity="bottom"
and use textView.append("\n"+"New Input Text."); for new input text;
You are almost there. Just add a few more things to achieve this,
First of all add those properties in your TextView
android:maxLines = "AN_INTEGER"
android:scrollbars = "vertical"
android:gravity="bottom"
Secondly as usual use,
tView.setMovementMethod(new ScrollingMovementMethod());
This should solve your problem.
I would suggest wrapping your TextView in a ScrollView
<ScrollView
android:id="#+id/sView"
android:layout_below="#+id/iView"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_centerHorizontal="true" >
<TextView
android:id="#+id/tView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:maxLines="500"
android:scrollbars="vertical"
android:gravity="bottom" />
</ScrollView>
You can append new text by doing
public void appendAndScrollDown(String someText) {
tView.append("\n" + someText);
sView.fullScroll(View.FOCUS_DOWN);
}
