【Java】 android屏蔽HOME键的方法

作者:晨曦 / 发布于2016/3/21/ 597

在相应的Activity中加入：

public void onAttachedToWindow()
{  
       this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);     
       super.onAttachedToWindow(); 	
}


下面是FRAMWORK层的代码，里面的type == WindowManager.LayoutParams.TYPE_KEYGUARD条件是返回FALSE

if (code == KeyEvent.KEYCODE_HOME) {
 
            // If a system window has focus, then it doesn't make sense
            // right now to interact with applications.
            WindowManager.LayoutParams attrs = win != null ? win.getAttrs() : null;
            if (attrs != null) {
                final int type = attrs.type;
                if (type == WindowManager.LayoutParams.TYPE_KEYGUARD
                        || type == WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG) {
                    // the "app" is keyguard, so give it the key
                    return false;
                }
                final int typeCount = WINDOW_TYPES_WHERE_HOME_DOESNT_WORK.length;
                for (int i=0; i<typeCount; i++) {
                    if (type == WINDOW_TYPES_WHERE_HOME_DOESNT_WORK[i]) {
                        // don't do anything, but also don't pass it to the app
                        return true;
                    }
                }
            }
