[Android開發]簡單版仿淘口令複製彈出框功能

使用Android系統的粘貼板管理服務及ClipboardManager通過addPrimaryClipChangedListener添加Listener來監聽粘貼板的狀態，很很簡單的一個小功能~

1.首先創建一個Service在後臺運行：

        Intent intent = new Intent(this,MainService.class);
        startService(intent);

另外同時在OnResume()中獲得粘貼板複製的內容，用於在APP未啓動或者Service被關閉時重新啓動APP來彈出口令窗口

	@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		super.onResume();
		ClipboardManager mClipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
		Log.e("Copylistenerdemo", mClipboardManager.getPrimaryClip().getItemAt(0).getText().toString());
	}

2.在Service管理粘貼板服務：

	mClipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
	mClipboardManager.addPrimaryClipChangedListener(mPrimaryClipChangedListener);

3.在onPrimaryClipChanged()做想要的事情，例如彈出框：

使用WindowManager來顯示彈出框

	LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);       
        final View floatView = layoutInflater.inflate(R.layout.floater, null);  
		final WindowManager mWindowManager = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);  
        LayoutParams params = new WindowManager.LayoutParams();  
        params.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;//系統內部錯誤提示，顯示於所有內容之上
        params.format = PixelFormat.RGBA_8888; 
        params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL  
                | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;  //當窗口可以獲得焦點（沒有設置FLAG_NOT_FOCUSALBE選項）時，仍然將窗口範圍之外的點設備事件（鼠標、觸摸屏）發送給後面的窗口處理
        params.width = WindowManager.LayoutParams.MATCH_PARENT; 
        params.height = WindowManager.LayoutParams.WRAP_CONTENT;  
        params.gravity = Gravity.LEFT | Gravity.TOP;  
        params.x = 0;  
        params.y = 0;
        mWindowManager.addView(floatView, params);
        ObjectAnimator animatorShow = ObjectAnimator.ofFloat(floatView, "alpha", 0.0f,1.0f);
        animatorShow.setDuration(500);
        animatorShow.start();
        ObjectAnimator animatorHide = ObjectAnimator.ofFloat(floatView, "alpha", 1.0f,0.0f);
        animatorHide.setDuration(500);
        animatorHide.setStartDelay(3000);
        animatorHide.start();

點擊彈出框，跳轉activity

        floatView.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				Toast.makeText(MainService.this, "點擊淘口令", Toast.LENGTH_SHORT).show();
				Intent intent = new Intent();
				intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
				intent.setClass(MainService.this, xxActivity.class);
				startActivity(intent);
			}
		});

很簡單的小功能，不過應用的實際過程應該還會出現一些待解決的小問題
