閑來無事猫缭，搞一波懸浮球，此球：
- 無需權(quán)限
- 主要代碼只有一個(gè)類炎辨，簡簡單單放進(jìn)自己的工程
- 懸浮球可以用來干啥：
- 打開側(cè)滑界面
- 打開一排小按鈕
- 打開客服等等
- 功能：
- 顯示紅點(diǎn)（接收到信息等場(chǎng)景）
- 關(guān)閉紅點(diǎn)（關(guān)閉消息提示）
- 自動(dòng)貼邊
- 顯示球
- 隱藏球
- 自定義點(diǎn)擊事件及回調(diào)
- 可以說你能想到自定義的都可以自定義瞳腌，因?yàn)橄旅鏁?huì)給出代碼谴忧，任君擴(kuò)展
先看看效果如何，圖片大小有限制努咐，所以我錄得比較急一些苦蒿，效果不是很好。

這個(gè)懸浮球渗稍，我自覺還是蠻棒的佩迟，以下給出主要代碼：
MainActivity.class
public class MainActivity extends Activity {
protected Button toButton,noButton,exitButton,jumpButton;
protected Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initVariables();

//造個(gè)懸浮球，并顯示出來
SyFloatView.getInstance(this).show();
//這里可以根據(jù)需求竿屹，添加點(diǎn)擊事件處理
SyFloatView.getInstance(this).setListener(new SyFloatView.FloatingLayerListener() {
@Override
public void onClick() {
//點(diǎn)擊懸浮球事件
Log.e("MainAc","這是 點(diǎn)擊懸浮球 監(jiān)聽回調(diào)报强。");
}
@Override
public void onClose() {
//關(guān)閉懸浮球事件
Log.e("MainAc","這是 關(guān)閉懸浮球 監(jiān)聽回調(diào)。");
}
});
}
@Override
protected void onResume() {
super.onResume();
//顯示懸浮球：進(jìn)入APP拱燃、登陸成功等場(chǎng)景下
SyFloatView.getInstance(mContext).display();
}
@Override
protected void onPause() {
super.onPause();
//隱藏懸浮球：回到桌面等場(chǎng)景
SyFloatView.getInstance(mContext).hide();
}
//關(guān)閉APP
protected void exitApp(){
//干掉懸浮球：可以在關(guān)閉APP秉溉、注銷賬號(hào)等場(chǎng)景下使用
SyFloatView.getInstance(mContext).close();
System.exit(0);
finish();
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch(keyCode){
case KeyEvent.KEYCODE_BACK:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("退出提示");
builder.setMessage("確認(rèn)要退出APP？");

builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { //設(shè)置取消按鈕
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create().show();
break;
}
return true;
}
//初始化
protected void initVariables() {

}
//初始化視圖
protected void initViews(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
toButton = (Button) findViewById(R.id.to_btn);
noButton = (Button) findViewById(R.id.no_btn);
exitButton = (Button) findViewById(R.id.exit_app_btn);
jumpButton = (Button) findViewById(R.id.jump_btn);
//來消息了扼雏，顯示消息紅點(diǎn)
toButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SyFloatView.getInstance(mContext).redDotVisible();
}
});
//朕已閱坚嗜，點(diǎn)擊關(guān)掉消息紅點(diǎn)
noButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SyFloatView.getInstance(mContext).redDotViewGone();
}
});
//關(guān)閉APP
exitButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

}
});
//跳轉(zhuǎn)下一個(gè)Activity
jumpButton.setOnClickListener(new View.OnClickListener() {

Intent i = new Intent(MainActivity.this,MainActivity2.class);
startActivity(i);

這個(gè)懸浮球碟绑，是別人送我的一個(gè)球俺猿，我自己修修改改縫縫補(bǔ)補(bǔ)就發(fā)來了，大家鼓掌??格仲。
有個(gè)小問題押袍，華為現(xiàn)在手勢(shì)直接左右側(cè)滑屏可以退出APP，這個(gè)退出又不似真的殺死APP凯肋。再打開APP懸浮球就出不來了谊惭，也不知道哪里導(dǎo)致的，莫名其妙侮东，我目前是把返回按鈕那里直接處理了一下圈盔，彈出個(gè)詢問是否退出。有人如果發(fā)現(xiàn)原因的話悄雅，麻煩留言教我一哈驱敲。
最后附上demo源碼地址，方便你把工程放進(jìn)你的項(xiàng)目宽闲，能幫我再優(yōu)化一下那就更加萬分感謝了众眨。
