How to get animation in android?

android, android-layout, animation, xml

Solution

Yes I did it. Here is my code, may be it help others...

In my MainActivity.

public class MainActivity extends ActionBarActivity {

 private View hiddenPanel;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    hiddenPanel = findViewById(R.id.hidden_panel);
        }

 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
            Animation bottomDown = AnimationUtils.loadAnimation(this,
                    R.anim.bottom_down);

            hiddenPanel.startAnimation(bottomDown);
            hiddenPanel.setVisibility(View.GONE);
        }
    }

    private boolean isPanelShown() {
        return hiddenPanel.getVisibility() == View.VISIBLE;
    }

}

In my activity_main

<?xml version="1.0" encoding="utf-8"?>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:text="@string/hello_world" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:text="@string/hello_world" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:onClick="slideUpDown"
    android:text="Slide up / down" />

<RelativeLayout
    android:id="@+id/hidden_panel"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    android:visibility="gone" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name"
        android:layout_centerInParent="true"
        android:onClick="slideUpDown" />
</RelativeLayout>

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>

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>

Problem

Actually I have an `Linear Layout` which is `matchParent`(in `width` and `height`), and now I need to create a another `layout`(below that `linearLayout`) which must not be visible initially. And when my activity will run then I want to animate that hided layout. The hided `layout` must be come from below to up side. I don't know how to achieve this animation ?? I don't know how to create the layout which must not be visible initially and after a delay it must show from below of the screen and come up side ??? here is my code of xml file ``` <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:id="@+id/imageupLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:orientation="vertical" > <ImageView android:id="@+id/imgview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:background="@drawable/logo" /> </LinearLayout> <LinearLayout android:id="@+id/hided_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:background="#56a24b" android:orientation="vertical" android:visibility="visible" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_marginTop="15dip" android:background="@drawable/btn_bg" android:gravity="center" > <Button android:id="@+id/btn_login" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="2dip" android:background="@drawable/btn_login" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_marginTop="10dip" android:background="@drawable/btn_bg" android:gravity="center" > <Button android:id="@+id/btn_register" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="2dip" android:background="@drawable/btn_register" /> </LinearLayout> <TextView android:id="@+id/tv_just_explore" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="20dip" android:layout_marginTop="20dip" android:gravity="center" android:text="JUST EXPLORE" android:textColor="#FFFFFF" android:textSize="15dip" android:textStyle="bold" /> </LinearLayout> </LinearLayout> ```
