Android - Add subview after animation

Android - Add subview after animation - android

I'm trying to add a subview below another view after an animation. anyone have any idea what i'm doing wrong?
this.animate().translationY(newY - 170).setDuration(500).withEndAction(new Runnable() {
#Override
public void run() {
clearAnimation();
RouteBreakDownLayout routeBreakDownLayout = new RouteBreakDownLayout(mContext);
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, R.id.selected_route_layout);
routeBreakDownLayout.setLayoutParams(p);
addView(routeBreakDownLayout);
}
}).start();
Here is the XML for the layout. I have a scrollview embeded which will hold the content that needs to be animated in.

What goes wrong for you in your code-snippet?
Here's working example I came up with:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/containerRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="#+id/headerView"
android:background="#00FF00"
android:layout_width="match_parent"
android:layout_height="25dp"/>
<View
android:id="#+id/detailsView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="40dp"
android:clickable="true"
android:background="#FF0000"/>
</RelativeLayout>
And MainActivity is
package klogi.com.animationstestapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.RelativeLayout;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final View detailsView = findViewById(R.id.detailsView);
final View headerView = findViewById(R.id.headerView);
final RelativeLayout container = (RelativeLayout)findViewById(R.id.containerRelativeLayout);
container.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
detailsView.animate().translationY(-detailsView.getY()).setDuration(500).withEndAction(new Runnable() {
#Override
public void run() {
Button additionalButton = new Button(MainActivity.this);
additionalButton.setText("Additional button");
RelativeLayout.LayoutParams additionalButtonParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
additionalButtonParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
additionalButton.setLayoutParams(additionalButtonParams);
container.addView(additionalButton);
}
}).start();
headerView.animate().translationY(detailsView.getHeight()).setDuration(500).start();
}
});
}
}
It works just as expected.
Have you tried to add your control(RouteBreakDownLayout) without animation? Does it work? It can be something like control is actually adding, but it's out of the viewport, etc. - so far, I can just guessing.

Expected Result ( Working correctly on Tablet with Android 4.4.2 with below code)
Actual Results ( Tested on multiple phones with OS >= 8.1.0)

I Have tried your code but unable to reproduce this output
For me your code is working fine check the output
Result in Oreo
Result in android pie
Result in android Q
as per my opinion you should use
You should use RecyclerView with GridLayoutManager
Follow this sample code
Add one recyclerview in your activity layout xml file
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="0dp"
android:gravity="center">
<androidx.recyclerview.widget.RecyclerView
android:layout_width="wrap_content"
android:id="#+id/gridRecyclerView"
android:layout_centerInParent="true"
android:layout_height="wrap_content"/>
</RelativeLayout>
Now inside your activity set GridLayoutManager to your RecyclerView
GridLayoutManager (Context context,
int spanCount)
Creates a vertical GridLayoutManager
Parameters
context Context: Current context, will be used to access resources.
spanCount int: The number of columns in the grid
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.GridLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
public class JavaActivity extends AppCompatActivity {
RecyclerView myRecyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_java);
myRecyclerView = findViewById(R.id.gridRecyclerView);
GridLayoutManager gridLayoutManager = new GridLayoutManager(JavaActivity.this, 6);
myRecyclerView.setLayoutManager(gridLayoutManager);
myRecyclerView.setAdapter(new MyAdapter(this));
}
}
Create one adapter class RecyclerView like this
import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
private Context context;
public MyAdapter(Context context) {
this.context = context;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.row_list_item, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
if (position%2==0){
holder.imgBanner.setBackgroundColor(Color.BLUE);
}else {
holder.imgBanner.setBackgroundColor(Color.GREEN);
holder.imgBanner.setImageResource(R.drawable.red_heart);
}
}
#Override
public int getItemCount() {
return 36;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
ImageView imgBanner;
public MyViewHolder(#NonNull View itemView) {
super(itemView);
imgBanner = itemView.findViewById(R.id.imgBanner);
}
}
}
Create one layout file for RecyclerView item
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_margin="2dp"
android:orientation="vertical">
<ImageView
android:id="#+id/imgBanner"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
/>
</RelativeLayout>

Try with a padding like this:
<RelativeLayout
android:id="#+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="someDp" ->>>> Padding
android:paddingRight="someDp" ->>>> Padding
android:layout_above="#+id/horizontal_divider"
android:layout_below="#id/toolbar"
android:gravity="center">
<TableLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tblLayout"
android:gravity="center"
android:shrinkColumns="*"
android:padding="0dip"
android:layout_margin="0dip"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"></TableLayout>
</RelativeLayout >

Layout of fragment disintegrates when it dynamically replaces framelayout

I have an app with MainActivity that contains a FrameLayout which would be replaced by a fragment based on which item is clicked in the bottom layout. I have a fragment named "bookings" that must appear in the body area when "Bookings" option is clicked. The "bookings" fragment contains a spinner and a button that are placed at the center of screen inside of RelativeLayout. When the fragment's layout is placed directly inside of body of MainActivity, the spinner and button is centered, just the way I want it to be.

Change height of FrameLayout to match_parent from wrap_content
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottompanel"
android:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_frame"/>
</LinearLayout>

You have match_parent in the height for fragment layout. Try changing it to wrap_content and see if it works

included bottom layout for all the android activites with onclick events not working

I am new to android development. I want to include the same horizontal Scroll view in all android activities.I have defined the layout and Onclick events in one separate activity and extended that class with other activites.But the onclick events are not working
here is my Base Activity
public class Footer extends AppCompatActivity implements View.OnClickListener {
private ImageView img_school, img_group, img_news, img_schemes, img_jobs, img_gallery, img_goddess, img_services, img_census, img_address, img_abt_us;
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.imgs_school:
Intent i = new Intent(Footer.this, SchoolActivity.class);
startActivity(i);
break;
case R.id.imgs_galary:
Intent gi = new Intent(Footer.this, GalleryActivity.class);
startActivity(gi);
break;
case R.id.imgs_events:
Intent ni = new Intent(Footer.this, EventsActivity.class);
startActivity(ni);
break;
case R.id.imgs_abtus:
break;
case R.id.imgs_jobs:
Intent ji = new Intent(Footer.this, JobsActivity.class);
startActivity(ji);
break;
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_footer);
initAll();
img_gallery.setOnClickListener(this);
img_school.setOnClickListener(this);
img_news.setOnClickListener(this);
img_jobs.setOnClickListener(this);
img_abt_us.setOnClickListener(this);
}
public void initAll() {
img_school = findViewById(R.id.imgs_school);
img_news = findViewById(R.id.imgs_events);
img_jobs = findViewById(R.id.imgs_jobs);
img_gallery = findViewById(R.id.imgs_galary);
img_abt_us = findViewById(R.id.imgs_abtus);
}
}

And i am extending this activity with other classes
such as
public class SchoolActivity extends Footer {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_school);
}
}
And its activity_school xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.evoqis.manovaru.SchoolActivity">
<include layout="#layout/activity_footer"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
But the onclick events are not happening.
Thanks in adavance

Here is the problem:
In subclass you call:
super.onCreate(savedInstanceState);
Which calls:-
setContentView(R.layout.activity_footer); //which creates a new views
initAll(); //which finds views by id
img_gallery.setOnClickListener(this); //setting listeners.
and then in subclass you call:
setContentView(R.layout.activity_school); which creates new view, and overrides all the listeners you have set in superclass.
How to fix it
Move
img_gallery.setOnClickListener(this);
img_school.setOnClickListener(this);
img_news.setOnClickListener(this);
img_jobs.setOnClickListener(this);
img_abt_us.setOnClickListener(this);
Inside public void initAll(), and in subclass do this:
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_school);
initAll();
Also you can remove onCreate() method from superclass.

how can i make my app compatible with all screen sizes without making different layout files for it?

I have a linear layout for buttons so when i run the app on different mobiles some of the buttons get hidden. As my app is ready in terms of code so i want some short technique to make it compatible for all screen sizes.

Percent Relative Layout
https://developer.android.com/reference/android/support/percent/PercentRelativeLayout.html
Constraint Layout
https://developer.android.com/training/constraint-layout/index.html

Use layout_weight. Research about them. I have started using layout_weight and they adjust to any screen size. Weights are used in LinearLayouts and TableLayouts. There may be more but those are the two i have used them in. If you want space in between items, go to the layout text screen and type
<View
and press enter. it should guide you from there. Views also can have weight too.

do not give any fix size to button or TextView
as per above code you give
<ImageView
android:id="#+id/about_btn"
android:layout_width="50dp"
android:layout_height="50dp"
android:src="#drawable/about"
android:layout_gravity="center"
android:elevation="4dp"/>``
Imageview you give fix size 50dp for(height and width).Image view Hight&Width never change when you run different mobile phone.
so most of use Wrap_content and Match_Parent
