FrameLayout with two includes only set correctly the first one. Why?

I have a ScollView Layout with a FrameLayout that includes two different layouts. If some condition is met, I set one or the other as visible.
dialog_interface_login.xml
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:font="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/color_white"
android:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/landing_login_view"/>
<include layout="#layout/mobile_login_view"/>
</FrameLayout>
</ScrollView>
My class:
final View v = inflater.inflate(R.layout.dialog_interface_login, container, false);
View mobileLayout = v.findViewById(R.id.mobile_root_view);
View landingLayout = v.findViewById(R.id.landing_root_view);
if (landingLogin) {
mobileLayout.setVisibility(View.INVISIBLE);
landingLayout.setVisibility(View.VISIBLE);
} else {
mobileLayout.setVisibility(View.VISIBLE);
landingLayout.setVisibility(View.INVISIBLE);
}
Inside theese layouts that was set on the include, I have another include:
landing_login_view.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:font="http://schemas.android.com/apk/res-auto"
android:id="#+id/landing_root_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/color_white"
android:paddingLeft="#dimen/twenty_eight_dp"
android:paddingRight="#dimen/twenty_eight_dp"
android:orientation="vertical">
...
<include layout="#layout/sms_login"/>
...
</LinearLayout>
And mobile_login_view.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:font="http://schemas.android.com/apk/res-auto"
android:id="#+id/mobile_root_view"

android:paddingLeft="#dimen/twenty_eight_dp"

Programmatically, I set some behaviors, such as a mask for the phone field etc.
But these behaviors that are programmatically configured in sms_login.xml will only occur if the layout is set first in my dialog_interface_login.xml. I have the same include, with the same information, but only works on the first one that is defined at ContainerLayout. Even the onclick event does not trigger.
Do you have any idea why? Is it possible to define two different includes?
----- Edited -----
Including some actions done
v.findViewById(R.id.btn_sms_login).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (phoneWatcher.isPhoneNumberValid()) {
String phoneNumber = etPhoneNumber.getText().toString().replaceAll("\\D+", "");
onSuccessClick.OnSuccess(phoneNumber);
LoginInterfaceVivoSyncDialog.this.dismiss();
}
}
});

You should use Visibility.GONE instead of INVISIBLE
You can directly assign id to include block why you made two extra different layouts to give just an id.
I was shocked to see #dimen/twelve_dp (really shocked). What is use of dimens.xml if you are writing twelve_dp there. You can directly write 12dp. It should be generic like space_small or space_large or text_size_small.
Also removed some extra wrapping layouts from your xml.

Do you have any idea why?
This happens because findViewById(R.id.xyz) returns the first View which has the requested attribute android:id="#+id/R.id.xyz".
Quoting from the documentation on View:
Finds the first descendant view with the given ID, the view itself if the ID matches getId(), or null if the ID is invalid (< 0) or there is no matching view in the hierarchy.
To access the correct View, you'll have to use some property which makes it unique. In your case, for example the value R.id.et_phone_number can be found twice in the FrameLayout. But if you write
View myView = mobileLayout.findViewById(R.id.et_phone_number);
then there will be just one child View of mobileLayout with the requested id.
Your code snippet can be changed as follows:
final View v = inflater.inflate(R.layout.dialog_interface_login, container, false);
View mobileLayout = v.findViewById(R.id.mobile_root_view);
View landingLayout = v.findViewById(R.id.landing_root_view);
if (landingLogin) {
mobileLayout.setVisibility(View.INVISIBLE);
landingLayout.setVisibility(View.VISIBLE);
} else {
mobileLayout.setVisibility(View.VISIBLE);
landingLayout.setVisibility(View.INVISIBLE);
}
setupViewGroup(mobileLayout);
setupViewGroup(landingLayout);
The method setupViewGroup(View layout) should look like this:
private void setupViewGroup(View layout)
{
final EditText etPhoneNumber = layout.findViewById(R.id.et_phone_number);
layout.findViewById(R.id.btn_sms_login).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (phoneWatcher.isPhoneNumberValid()) {
String phoneNumber = etPhoneNumber.getText().toString().replaceAll("\\D+", "");
// ...
}
}
});
}
By calling findViewById() on layout you will get the desired child Views of the ViewGroups which were added by using <include .../>

ImageView background in not setting multiple times

I am working on an android project, in which I need to set ImageView
background (ascending icon and descending icon) multiple times. to do
this I am doing it with a clicking variable like:
sortBookedOnLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
pickUpImage.setBackgroundResource(R.drawable.ascending);
vouchredImage.setBackgroundResource(R.drawable.ascending);
cancledImage.setBackgroundResource(R.drawable.ascending);
if(Constant.bookedOn == 1) {
Log.d(TAG, "FliteronClick:1 ");
bookedonImage.setImageDrawable(mContext.getResources().getDrawable(R.drawable.ascending_active));
// int ascending_active_b = R.drawable.ascending_active;
// bookedonImage.setBackgroundResource(ascending_active_b);
// bookedonImage.setImageDrawable(mContext.getResources().getDrawable( R.drawable.ascending_active));
// bookedonImage.setBackground(mContext.getResources().getDrawable(R.drawable.ascending_active));
// ivPickUpTxt.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ascending_active, 0);
Constant.bookedOn = 2;
}else if(Constant.bookedOn == 2){
Log.d(TAG, "FliteronClick:2 ");
bookedonImage.setImageDrawable(mContext.getResources().getDrawable(R.drawable.decending_active));
// bookedonImage.setImageResource(android.R.color.transparent);
// int decending_active_b = R.drawable.decending_active;
// bookedonImage.setBackgroundResource(decending_active_b);
// bookedonImage.setImageDrawable(mContext.getResources().getDrawable( R.drawable.decending_active));
// ivPickUpTxt.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.decending_active, 0);
Constant.bookedOn = 1;
}
}
}
});
And My Xml layout is just like:
<LinearLayout
android:id="#+id/sortBookedOnLayout"
android:orientation="horizontal"
android:background="#color/white"
android:weightSum="2"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_weight="1.8"
android:layout_width="0dp"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/bookedOntxtLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/ivPickUpTxt"
style="#style/editTextTheme"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/edittext_background"
android:drawableLeft="#drawable/cal2"
android:drawablePadding="10dp"
android:hint="#string/booked_on"
android:inputType="text"
android:maxLines="1"
android:padding="10dp"
android:textColor="#000000"
android:textCursorDrawable="#drawable/cursor_drawable"
android:textSize="#dimen/filter_text_size"
/>
</RelativeLayout>
</LinearLayout>
<LinearLayout
android:layout_weight=".2"
android:layout_width="0dp"
android:layout_height="match_parent">
<ImageView
android:id="#+id/booedOnImage"
android:scaleType="fitXY"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/ascending"
/>
</LinearLayout>
</LinearLayout>
Screenshot of my layout.
in this image i am going to click on BookedOn layout.
And my targetSdkVersion 25
I have tried it multiple ways as I commented but image icon is not
reflecting on imageView. any help will be appreciable.Thanks.

Try this:
qImageView.setBackgroundResource(R.drawable.thumbs_down);
and add android:scaleType:fitxy
<ImageView
android:id="#+id/booedOnImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitxy"
android:background="#drawable/ascending"/>
(or) Try programmatically
imgview.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
Here's a thread that talks about the differences between the two methods.
I Understand your problem...You are not set the width of the LinearLayout
<LinearLayout
android:layout_weight=".2"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<ImageView
android:id="#+id/booedOnImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/abc_btn_rating_star_off_mtrl_alpha"
/>
</LinearLayout>

change the background color of a certain part of the screen relative to some element in android

I have an ImageView and a TextView and I want to change the color of the background from the bottom to half the height of my ImageView. I tried to do that with a View like this:
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.MainActivity">
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:background="#color/cyan"
android:id="#+id/blue_background" />
<TextView
android:id="#+id/credits"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:textAlignment="center"
android:textColor="#color/white"
android:text="#string/credits"/>
<ImageView
android:id="#+id/logo"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_above="#id/credits"
android:layout_below="#id/resume_button"
android:layout_centerHorizontal="true"
android:adjustViewBounds="true"
android:scaleType="fitCenter"
android:src="#drawable/logo"/>
</RelativeLayout>
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView logo = (ImageView) findViewById(R.id.logo);
TextView credits = (TextView) findViewById(R.id.credits);
View background_blue = (View) findViewById(R.id.blue_background);
background_blue.getLayoutParams().height = credits.getLayoutParams().height + (logo.getLayoutParams().height / 2);
}
but it doesn't work, I get the entire background as blue instead of just the part I am interested in.

Use ViewTreeObserver
final ImageView logo = (ImageView) findViewById(R.id.logo);
ViewTreeObserver vto = logo.getViewTreeObserver();
vto.addOnGlobalLayoutListener (new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
logo.getViewTreeObserver().removeOnGlobalLayoutListener(this);
int width = logo.getMeasuredWidth();
int height = logo.getMeasuredHeight();
background_blue.getLayoutParams().height = credits.getLayoutParams().height + (height / 2);
}
});

Try this workaround
Replace this
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:background="#color/cyan"
android:id="#+id/blue_background" />
With this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<View
android:id="#+id/blue_background"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#color/cyan" />
</LinearLayout>
and remove this line from Main Activity
background_blue.getLayoutParams().height = credits.getLayoutParams().height + (logo.getLayoutParams().height / 2);

TranslateAnimation move tomake other views appear

I'm using a TranslateAnimation to make a fragment (GoogleMap) sliding down to give space to an EditText and a TextView to be visible.
so I used this:
text: TextView
edit: EditText
MapLayout: a LinearLayout that contains the Map
Animation animation = new TranslateAnimation(
MapLayout.getX(), MapLayout.getY(),MapLayout.getY(), text.getHeight()+edit.getHeight());
The problem is that I can't make the slide because text.getHeight()+edit.getHeight() returns 0 so there's no slide!
I tried using a number (100 for exemple), the slide is made, but it's different between the devices, I tested on a Galaxy S3 and the slide is not complete, there's still a part of the EditText which is not visible, as for the emulator it worked ok.
When I tried to make the number a bit bigger, so the slide will be longer (200 for exemple), well... the slide was good for the S3, but i was big for the emulator.
So what I want to know is that if there's any way to make the slide move to a point, without depending on the device, I mean without using pixels; so the slide will work perfectly in any device/
I hope that my problem is clear.
Thank you
Update: I don't if this will help, I added a Toast message, show the height of the EditText and the TextView, in the Emulator it says: 85 and in the S3 it says 181
So yeah, I need to make the map slide down in any device like I said
MainActivity:
protected Animation animation;
protected LinearLayout MapLayout;
protected EditText edit;
protected TextView text;
MapLayout = (LinearLayout)findViewById(R.id.MapLayout);
edit = (EditText)findViewById(R.id.Recherche);
text = (TextView)findViewById(R.id.CaptionRecherche);
Toast.makeText(context, "Height: "+(edit.getHeight()+text.getHeight()), 1000).show();
animation = new TranslateAnimation(MapLayout.getX(), MapLayout.getY(), MapLayout.getY(), text.getHeight()+edit.getHeight());
animation.setDuration(1000);
animation.setFillAfter(true);
MapLayout.startAnimation(animation);
Main XML:

As a part of my application, I have a status bar which contains some text. This status bar is hidden until the user clicks a button at which point it slides down (hiding the topmost content of the layout below).
The code I use to get the correct height of the hidden status bar:
private int hiddenStatusHeight;
private int currentStatusBarHeight;
private void getStatusBarHeight() {
final ViewTreeObserver observer = hiddenStatus.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#SuppressLint("NewApi") #SuppressWarnings("deprecation") #Override public void onGlobalLayout() {
hiddenStatus.measure(MeasureSpec.UNSPECIFIED,
MeasureSpec.UNSPECIFIED);
hiddenStatusHeight = hiddenStatus.getMeasuredHeight();
currentStatusBarHeight = statusBar.getHeight();
ViewTreeObserver obs = hiddenStatus.getViewTreeObserver();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
obs.removeOnGlobalLayoutListener(this);
} else {
obs.removeGlobalOnLayoutListener(this);
}
}
});
}
The code that is executed when the button is clicked:
private OnClickListener ExpandClickListener = new OnClickListener() {
#Override public void onClick(View v) {
boolean isExpanded = (Boolean) expandButton
.getTag(R.id.TAG_EXPANDED);
int originalHeight = (Integer) expandButton
.getTag(R.id.TAG_ORIGINAL_HEIGHT);
if (isExpanded) {
expandButton.setTag(R.id.TAG_EXPANDED, false);
expandButton.setImageResource(R.drawable.ic_action_down);
// statusBar.setLayoutParams(new FrameLayout.LayoutParams(
// LayoutParams.MATCH_PARENT, originalHeight));
Log.d(TAG, "Collapsing to " + originalHeight);
ValueAnimator va = ValueAnimator.ofInt(currentStatusBarHeight,
originalHeight);
va.setDuration(500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
statusBar.getLayoutParams().height = value.intValue();
statusBar.requestLayout();
}
});
va.start();
} else {
expandButton.setTag(R.id.TAG_EXPANDED, true);
expandButton.setImageResource(R.drawable.ic_action_collapse);
currentStatusBarHeight = originalHeight + hiddenStatusHeight;
// statusBar.setLayoutParams(new FrameLayout.LayoutParams(
// LayoutParams.MATCH_PARENT, currentStatusBarHeight + 15));
Log.d(TAG, "Expanding to " + originalHeight + "+"
+ hiddenStatusHeight + "=" + currentStatusBarHeight);
ValueAnimator va = ValueAnimator.ofInt(originalHeight,
currentStatusBarHeight);
va.setDuration(500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
statusBar.getLayoutParams().height = value.intValue();
statusBar.requestLayout();
}
});
va.start();
}
}
};

Hope some of this may be helpful to you.
Just to mention it, I have asked a similar question where the visible layout is pushed downwards as the menu expands. So have a look at that if you rather want this behaviour: How to animate a slide in notification view that pushes the content view down
Happy coding

Add view to a vertical LinearLayout at bottom (programmatically)

I need to add views to a vertical Linearlayout at bottom programmatically. (Yes we know that, it's in the title).
Ok : i can add views to the linearlayout, it's not a problem. But it's for a chat, so i need to add views at the bottom for each message which is displayed. I don't find any attributes to the LinearLayout to do that.
Adding messages :
mHandler.post(new Runnable() {
#Override
public void run() {
TextView message = new TextView(ChatActivity.this);
String[] splitMessage = text.split(":");
message.setText(splitMessage[0]+"\n"+splitMessage[1]);
message.setGravity(Gravity.LEFT);
message.setMaxWidth(200);
message.setBackgroundColor(getResources().getColor(android.R.color.tertiary_text_light));
message.setTextColor(getResources().getColor(android.R.color.black));
message.setSingleLine(false);
mLayout.addView(message);
}
});
chat_layout.xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/live_obs_mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/empty"
android:orientation="vertical" >
<ScrollView
android:id="#+id/chat_layout"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="10" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:isScrollContainer="tue"
>
</LinearLayout>
</ScrollView>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="bottom"
android:orientation="horizontal" >
<EditText
android:id="#+id/edit_chat"
android:layout_width="wrap_content"
android:layout_height="45dp"
android:layout_gravity="left|center_vertical"
android:layout_weight="5" />
<Button
android:id="#+id/chat_submit"
android:layout_width="wrap_content"
android:layout_height="45dp"
android:layout_gravity="right|center_vertical"
android:onClick="onSubmit"
android:text="OK" />
</LinearLayout>
</LinearLayout>

You can do it pragmatically like this, this is just an example. You may want to change your code based on that.
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.mylayout);
TextView txt1 = new TextView(MyClass.this);
LinearLayout.LayoutParams layoutParams =
(RelativeLayout.LayoutParams) txt1.getLayoutParams();
layoutParams.addRule(LinearLayout.BOTTOM, 1);
txt1.setLayoutParams(layoutParams);
linearLayout.addView(txt1);
