This example shows you how to create animation using the default XML tag in a gridview.
This application demonstrates how to use the animateLayoutChanges tag in XML to automate
transition animations as items are removed from or added to a container.

Let’s have a look.
At first we will look at the layout XML.
layout_animations_by_default.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/addNewButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Add Button" /> <GridLayout android:id="@+id/gridContainer" android:layout_width="wrap_content" android:layout_height="wrap_content" android:animateLayoutChanges="true" android:columnCount="4" /></LinearLayout> |
Now the Activity that uses this XML to create the animation.
LayoutAnimationsByDefault.java
package com.example.animationdemo1;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.GridLayout;/** * This application demonstrates how to use the animateLayoutChanges tag in XML to automate * transition animations as items are removed from or added to a container. */public class LayoutAnimationsByDefault extends Activity { private int numButtons = 1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.layout_animations_by_default); final GridLayout gridContainer = (GridLayout) findViewById(R.id.gridContainer); Button addButton = (Button) findViewById(R.id.addNewButton); addButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Button newButton = new Button(LayoutAnimationsByDefault.this); newButton.setText(String.valueOf(numButtons++)); newButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { gridContainer.removeView(v); } }); gridContainer.addView(newButton, Math.min(1, gridContainer.getChildCount())); } }); }} |
