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:

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();
}
}
