本日學習：

透過 onBackPressed()、onSearchRequested()、onKeyDown() 事件
擷取 HOME,MENU,BACK & SEARCH Event

1. BACK 按鍵：透過 onBackPressed() 即可控制

@Override
public void onBackPressed() {
//顯示確認離開對話
new AlertDialog.Builder(MaintainStockOutInfo.this)
.setTitle("XX作業")
.setMessage("是否離開XX作業 ?")
.setPositiveButton("確認", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which)
{
finish();
//super.onBackPressed();
}
            })
            .setNegativeButton("取消",new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which)
            {
            }
            })
            .show();
}

2.  SEARCH 按鍵：透過 onSearchRequested() 即可控制

@Override
public boolean onSearchRequested() {
//super.onSearchRequested();

return false;
}

3. HOME、MENU 按鍵：透過 onAttachedToWindow()、 onKeyDown() 即可控制
    (亦可控制 BACK、SEARCH 按鍵)

@Override
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}
    
public boolean onKeyDown(int keyCode, KeyEvent event) {  if (keyCode == KeyEvent.KEYCODE_HOME || keyCode == KeyEvent.KEYCODE_MENU || keyCode == KeyEvent.KEYCODE_BACK || keyCode == KeyEvent.KEYCODE_SEARCH ) {
   return true;
}
   
return super.onKeyDown(keyCode, event);
}
