In Android 5.0, android:minSdkVersion="21", ObjectAnimator has a new constructors that enable you to animate coordinates along a path using two or more properties at once. Here is a example:
VIDEO package com.example.androidobjectanimator; import android.animation.ObjectAnimator; import android.app.Activity; import android.graphics.Path; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.ImageView; import android.widget.LinearLayout; import android.widget.TextView; public class MainActivity extends Activity { LinearLayout mainLayout; TextView textTitle; Button buttonMove; ImageView image; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mainLayout = (LinearLayout) findViewById(R.id.mainlayout); mainLayout.setOnClickListener(MyOnClickListener); textTitle = (TextView) findViewById(R.id.title); textTitle.setOnClickListener(MyOnClickListener); buttonMove = (Button) findViewById(R.id.buttonflip); buttonMove.setOnClickListener(MyOnClickListener); image = (ImageView) findViewById(R.id.image); image.setOnClickListener(MyOnClickListener); } OnClickListener MyOnClickListener = new OnClickListener() { @Override public void onClick(View v) { moveit(v); } }; private void moveit(final View view) { float x = view.getX(); float y = view.getY(); Path path = new Path(); path.moveTo(x + 0, y + 0); path.lineTo(x + 100, y + 150); path.lineTo(x + 400, y + 150); path.lineTo(x + 0, y + 0); ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(view, View.X, View.Y, path); objectAnimator.setDuration(3000); objectAnimator.start(); } } <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/mainlayout" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:orientation="vertical" tools:context="com.example.androidflipview.MainActivity" > <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="android-coding.blogspot.com" android:textSize="28dp" android:textStyle="bold" /> <Button android:id="@+id/buttonflip" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Move" /> <ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" /> </LinearLayout>
