自定义控件（22）---FloatView悬浮窗（1）
点击打开链接，现在demo。。。。
自定义控件（23）---FloatView悬浮窗（2）
提问：我的代码有个问题，初始化默认2个绿色的imageView打开状态，此刻点击，让其收回，在点击让其打开，结果bug是2个绿色的imageview位置没有正确的放置
但是这个demo在手机N5上显示正常的，重点看下这个打开的操作，不知道哪里错了，应该是不兼容的问题，望网友解答，多谢
public void open() {
ObjectAnimator anim2 = ObjectAnimator.ofFloat(btnEncryption, "x",
434.5f, 0f);
anim2.addListener(new AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {
if (animListener != null) {
animListener.onAnimOpenEnd(null);
}
}
@Override
public void onAnimationCancel(Animator animation) {
}
});
anim2.setDuration(DURAIION);
ObjectAnimator anim4 = ObjectAnimator.ofFloat(btnTransmission, "x",
434.5f, 225f);
anim4.setDuration(DURAIION);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.play(anim2).with(anim4);
animatorSet.start();
isOpen = true;
}
activity_main.xml看主界面的布局文件
<?xml version="1.0" encoding="utf-8"?>

MainActivity-看主界面的代码
package com.example.floatbutton;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

@Override

}
上面的service中的代码添加的布局文件
expandView = (HorizontalAniView) LayoutInflater.from(this).inflate( R.layout.floating, null);布局文件为 floating.xml
<?xml version="1.0" encoding="utf-8"?>
<com.example.floatbutton.HorizontalAniView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" />
HorizontalAniView
package com.example.floatbutton;

private boolean isOpen = true;
protected final int DURAIION = 300;
protected View root;
/**

*/
public HorizontalAniView(Context context, AttributeSet attrs) {
super(context, attrs);
InflaterView(context);
}
public HorizontalAniView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
InflaterView(context);
}
public HorizontalAniView(Context context) {
super(context);
InflaterView(context);
}
public View InflaterView(Context context) {
root = LayoutInflater.from(context).inflate(
R.layout.horizontal_ani_view, this);
btnEncryption = (ImageView) root.findViewById(R.id.btnEncryption);
btnTransmission = (ImageView) root.findViewById(R.id.btnTransmission);

btnMain.setOnClickListener(new OnClickListener() {
public void onClick(View v) {

}
});
return root;
}
private void toggle() {
if (isOpen)
close();
else
open();
}
/**

protected FloatViewListener.FloatViewAnimListener animListener;
public void setFloatViewAnimListener(
FloatViewListener.FloatViewAnimListener listener) {
this.animListener = listener;
}
public void open() {
ObjectAnimator anim2 = ObjectAnimator.ofFloat(btnEncryption, "x",
434.5f, 0f);
anim2.addListener(new AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {

}
@Override

});
anim2.setDuration(DURAIION);
ObjectAnimator anim4 = ObjectAnimator.ofFloat(btnTransmission, "x",
434.5f, 225f);
anim4.setDuration(DURAIION);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.play(anim2).with(anim4);
animatorSet.start();
isOpen = true;
}
public void close() {
ObjectAnimator anim2 = ObjectAnimator.ofFloat(btnEncryption, "x",
0f,434.5f);
anim2.setDuration(DURAIION);
ObjectAnimator anim4 = ObjectAnimator.ofFloat(btnTransmission, "x",

anim4.setDuration(DURAIION);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.play(anim2).with(anim4);
animatorSet.start();
isOpen = false;
}
}
上面代码中
root = LayoutInflater.from(context).inflate( R.layout.horizontal_ani_view, this);
加载的布局文件
horizontal_ani_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<ImageView
android:id="@+id/btnEncryption"
android:layout_width="60.33dp"
android:layout_height="60.33dp"
android:src="@drawable/bendi" />
<ImageView
android:id="@+id/btnTransmission"
android:layout_width="60.33dp"

android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginLeft="14.67dp"
android:src="@drawable/zhuicon" />
</LinearLayout>
另外涉及到的监听事件
FloatViewListener
package com.example.floatbutton;
public class FloatViewListener {
public interface FloatViewAnimListener {
public void onAnimOpenEnd(int[] location);
}
}
用到的权限
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
