安卓实现app全局按钮,类似366悬浮球

安卓app内部实现一个全局的悬浮按钮,类似于360的悬浮球可在app内部所有界面显示。主要还是来源于网上搜索的,经过自己整合和修改!效果如图,主要是一个工具类,

代码如下:

import android.content.Context;

import android.graphics.Color;

import android.graphics.PixelFormat;

import android.view.Gravity;

import android.view.LayoutInflater;

import android.view.MotionEvent;

import android.view.View;

import android.view.ViewGroup;

import android.view.WindowManager;

import com.mocoo.ezc.R;

import com.mocoo.ezc.utils.Log;

import com.mocoo.ezc.utils.SPUtil;

public class FloatView2 {

private Context c;

private int height=0;

private int width=0;

public FloatView2(Context c) {

this.c=c;

}

private WindowManager wm;

private View view;// 浮动按钮

WindowManager.LayoutParams params;

/**

* 添加悬浮View

* @param

*/

public void createFloatView() {

wm = (WindowManager) c.getSystemService(Context.WINDOW_SERVICE);

height = wm.getDefaultDisplay().getHeight();

width = wm.getDefaultDisplay().getWidth();

view = LayoutInflater.from(c).inflate(R.layout.floatview, null);

params = new WindowManager.LayoutParams();

params.type = WindowManager.LayoutParams.TYPE_BASE_APPLICATION;// 所有程序窗口的“基地”窗口,其他应用程序窗口都显示在它上面。

params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL

| WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;

params.format = PixelFormat.TRANSLUCENT;// 不设置这个弹出框的透明遮罩显示为黑色

params.type = WindowManager.LayoutParams.TYPE_TOAST;

params.width = WindowManager.LayoutParams.WRAP_CONTENT;

params.height = WindowManager.LayoutParams.WRAP_CONTENT;

params.gravity = Gravity.TOP | Gravity.LEFT;

int screenWidth = c.getResources().getDisplayMetrics().widthPixels;

int screenHeight = c.getResources().getDisplayMetrics().heightPixels;

params.y = screenHeight- height/3;//设置距离底部高度为屏幕三分之一

params.x = screenWidth;

view.setBackgroundColor(Color.TRANSPARENT);

view.setVisibility(View.VISIBLE);

view.setOnTouchListener(new View.OnTouchListener() {

// 触屏监听

float lastX, lastY;

int oldOffsetX, oldOffsetY;

int tag = 0;// 悬浮球 所需成员变量

@Override

public boolean onTouch(View v, MotionEvent event) {

final int action = event.getAction();

float x = event.getX();

float y = event.getY();

if (tag == 0) {

oldOffsetX = params.x; // 偏移量

oldOffsetY = params.y; // 偏移量

}

if (action == MotionEvent.ACTION_DOWN) {

lastX = x;

lastY = y;

} else if (action == MotionEvent.ACTION_MOVE) {

params.x += (int) (x – lastX) / 3; // 减小偏移量,防止过度抖动

params.y += (int) (y – lastY) / 3; // 减小偏移量,防止过度抖动

tag = 1;

wm.updateViewLayout(view, params);

} else if (action == MotionEvent.ACTION_UP) {

int newOffsetX = params.x;

int newOffsetY = params.y;

// 只要按钮一动位置不是很大,就认为是点击事件

if (Math.abs(oldOffsetX – newOffsetX) <= 20

&& Math.abs(oldOffsetY – newOffsetY) <= 20) {

if(l != null){

l.onClick(view);

}

} else {

if( params.x < width/2){

params.x=0;

}else{

params.x=width;

}

wm.updateViewLayout(view, params);

tag = 0;

}

}

return true;

}

});

wm.addView(view, params);

}

/**

* 点击浮动按钮触发事件,需要override该方法

*/

private View.OnClickListener l;

public void onFloatViewClick(View.OnClickListener l) {

this.l=l;

}

/**

* 将悬浮View从WindowManager中移除,需要与createFloatView()成对出现

*/

public void removeFloatView() {

if (wm != null && view != null) {

wm.removeViewImmediate(view);

// wm.removeView(view);//不要调用这个,WindowLeaked

view = null;

wm = null;

}

}

/**

* 隐藏悬浮View

*/

public void hideFloatView() {

if (wm != null && view != null&&view.isShown()) {

view.setVisibility(View.GONE);

}

}

/**

* 显示悬浮View

*/

public void showFloatView(){

if (wm != null && view != null&&!view.isShown()) {

view.setVisibility(View.VISIBLE);

}

}

public void updateViewLayout(){

if(wm !=null){

int screenWidth = (int)SPUtil.get(“ParamsX”,0);

int screenHeight = (int)SPUtil.get(“ParamsY”,0);

if(screenWidth == 0){

screenWidth = c.getResources().getDisplayMetrics().widthPixels;

}

if(screenHeight == 0){

screenHeight = c.getResources().getDisplayMetrics().heightPixels;

params.y = screenHeight- height/3;//设置距离底部高度为屏幕三分之一

}else{

params.y = screenHeight;

}

params.x = screenWidth;

wm.updateViewLayout(view, params);

}

}

}

FloatView2  是一个主要的工具类params.type = WindowManager.LayoutParams.TYPE_TOAST;这句话一定要设这样才能显示于所有界面之上,用法如下(可直接在MainActivi的onCreate里面直接创建,在destory记得调用removeFloatView()方法):

floatView2 = new FloatView2(this);

floatView2.createFloatView();

floatView2.onFloatViewClick(new View.OnClickListener() {

@Override

public void onClick(View v) {

//这边是点击悬浮按钮的响应事件

}

到这这里悬浮按钮基本可以实现,剩下一个问题就是当app没有退掉直接点击Home键返回桌面,悬浮按钮仍可以显示,这里看需求是否需要我这里是不需要所以我做了处理,在Application里面做了一个监听,当退到后台发送一个广播到MainActivity里面调用hide的方法进行隐藏,回到前台再调用show的方法进行显示,MainActivity里面广播接受的方法就不贴了:

registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {

@Override

public void onActivityStopped(Activity activity) {

Log.v(“viclee”, activity + “onActivityStopped”);

count–;

if (count == 0) {

Intent intent = new Intent();

intent.putExtra(“isRunningForeground”, true);

intent.setAction(“com.mocoo.ezc.floatView”);

sendBroadcast(intent);

Log.v(“viclee”, “>>>>>>>>>>>>>>>>>>>切到后台  lifecycle”);

}

}

@Override

public void onActivityStarted(Activity activity) {

Log.v(“viclee”, activity + “onActivityStarted”);

if (count == 0) {

Intent intent = new Intent();

intent.putExtra(“isRunningForeground”, false);

intent.setAction(“com.mocoo.ezc.floatView”);

sendBroadcast(intent);

Log.v(“viclee”, “>>>>>>>>>>>>>>>>>>>切到前台  lifecycle”);

}

count++;

}

@Override

public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

Log.v(“viclee”, activity + “onActivitySaveInstanceState”);

}

@Override

public void onActivityResumed(Activity activity) {

Log.v(“viclee”, activity + “onActivityResumed”);

}

@Override

public void onActivityPaused(Activity activity) {

Log.v(“viclee”, activity + “onActivityPaused”);

}

@Override

public void onActivityDestroyed(Activity activity) {

Log.v(“viclee”, activity + “onActivityDestroyed”);

}

@Override

public void onActivityCreated(Activity activity, Bundle savedInstanceState) {

Log.v(“viclee”, activity + “onActivityCreated”);

}

});

如果有什么更好的优化方法请告知!谢谢
