I have a layout hidden from the view. On a button click I want it to slide up from the bottom pushing the entire screen contents upwards, very similar to how whatsapp shows emoticons panel in chat screen.
I have seen SlidingDrawer, that dosen't work for me. It requires an image as an handle which is shown at the center of the screen, I don't want that. It also slides over the existing screen content, I am looking for a way to move the existing content upwards.
Update 1:
I tried using the animations as suggested by Sanket Kachhela. But the hidden layout is never shown. Here is the code.
Layout (activity_main.xml):
<RelativeLayout
android:id="@+id/main_screen"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world"
android:layout_alignParentTop="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world"
android:layout_centerInParent="true"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Slide up / down"
android:layout_alignParentBottom="true"
android:onClick="slideUpDown"/>
</RelativeLayout>
<RelativeLayout
android:id="@+id/hidden_panel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/main_screen">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name" />
</RelativeLayout>
Activity (MainActivity.java):
package com.example.slideuplayout;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
public class MainActivity extends Activity {
private ViewGroup hiddenPanel;
private boolean isPanelShown;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hiddenPanel = (ViewGroup)findViewById(R.id.hidden_panel);
hiddenPanel.setVisibility(View.INVISIBLE);
isPanelShown = false;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void slideUpDown(final View view) {
if(!isPanelShown) {
// Show the panel
Animation bottomUp = AnimationUtils.loadAnimation(this,
R.anim.bottom_up);
hiddenPanel.startAnimation(bottomUp);
hiddenPanel.setVisibility(View.VISIBLE);
isPanelShown = true;
}
else {
// Hide the Panel
Animation bottomDown = AnimationUtils.loadAnimation(this,
R.anim.bottom_down);
hiddenPanel.startAnimation(bottomDown);
hiddenPanel.setVisibility(View.INVISIBLE);
isPanelShown = false;
}
}
}
Animations:
bottom_up.xml:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromYDelta="75%p"
android:toYDelta="0%p"
android:fillAfter="true"
android:duration="500" />
</set>
bottom_down.xml:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromYDelta="0%p"
android:toYDelta="100%p"
android:fillAfter="true"
android:interpolator="@android:anim/linear_interpolator"
android:duration="500" />
</set>
Any ideas how this can be done ?
Thanks.

Use these animations:
bottom_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="75%p" android:toYDelta="0%p"
android:fillAfter="true"
android:duration="500"/>
</set>
bottom_down.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="0%p" android:toYDelta="100%p" android:fillAfter="true"
android:interpolator="@android:anim/linear_interpolator"
android:duration="500" />
</set>
Use this code in your activity for hiding/animating your view:
Animation bottomUp = AnimationUtils.loadAnimation(getContext(),
R.anim.bottom_up);
ViewGroup hiddenPanel = (ViewGroup)findViewById(R.id.hidden_panel);
hiddenPanel.startAnimation(bottomUp);
hiddenPanel.setVisibility(View.VISIBLE);
You were close. The key is to have the hidden layout inflate to match_parent in both height and weight. Simply start it off as View.GONE. This way, using the percentage in the animators works properly.
Layout (activity_main.xml):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_screen"
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"

public class OffscreenActivity extends Activity {

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}
public void slideUpDown(final View view) {
if (!isPanelShown()) {
// Show the panel
Animation bottomUp = AnimationUtils.loadAnimation(this,
R.anim.bottom_up);
hiddenPanel.startAnimation(bottomUp);
hiddenPanel.setVisibility(View.VISIBLE);
}
else {
// Hide the Panel

hiddenPanel.startAnimation(bottomDown);
hiddenPanel.setVisibility(View.GONE);
}
}
private boolean isPanelShown() {
return hiddenPanel.getVisibility() == View.VISIBLE;
}
}
Only other thing I changed was in bottom_up.xml. Instead of
android:fromYDelta="75%p"
I used:
android:fromYDelta="100%p"
But that's a matter of preference, I suppose.
Try this below code, Its very short and simple.

My code to make animation slide up, slide down without XML
private static ObjectAnimator createBottomUpAnimation(View view,
AnimatorListenerAdapter listener, float distance) {
ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", -distance);
// animator.setDuration(???)
animator.removeAllListeners();
if (listener != null) {
animator.addListener(listener);
}
return animator;
}
public static ObjectAnimator createTopDownAnimation(View view, AnimatorListenerAdapter listener,
float distance) {
view.setTranslationY(-distance);
ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", 0);
animator.removeAllListeners();
if (listener != null) {
animator.addListener(listener);
}
return animator;
}
Using For slide down
createTopDownAnimation(myYellowView, null, myYellowView.getHeight()).start();
For slide up
createBottomUpAnimation(myYellowView, null, myYellowView.getHeight()).start();
Use this layout. If you want to animate the main view shrinking you'll need to add animation to the height of the hidden bar, buy it may be good enough to use the translate animation on the bar, and have the main view height jump instead of animate.

You just need to add some line in your app, please find it from below link:
Show and hide a View with a slide up/down animation
Just add an animation to your layout like this:
mLayoutTab.animate()
.translationYBy(120)
.translationY(0)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
You could define the mainscreen and the other screen that you want to scroll up as fragments. When the button on the mainscreen is pushed, the fragment would send a message to the activity which would then replace the mainscreen with the one that you want to scroll up and animate the replacement.
Ok, there are two possible approaches. The simplest - is to use a sliding menu library. It allows creating a bottom sliding menu, it can animate the top container to make bottom visible, it suports both dragging it with your finger, or animating it programmatically via button (StaticDrawer).
Harder way - if you want to use Animations, as was already suggested. With animations you must FIRST change your layouts. So try first to make your layout change to the final state without any animations whatsoever. Because it is very likely that you are not laying out your views properly in RelativeLayout, so even though you show your bottom view, it remains obscured by the top one. Once you achieved proper layout change - all you need to do is to is to remember translations before layout and apply translate animation AFTER layout.
