android学习笔记转--------------屏蔽返回键,home键以及其他实体按键
屏蔽键重写activiy的两个方法就行
屏蔽返回键
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
return true;
}
return super.onKeyDown(keyCode, event);
}
屏蔽home键和别的键不一样
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}
屏蔽其他实体按键
switch (keyCode) {
case KeyEvent.KEYCODE_HOME:
return true;
case KeyEvent.KEYCODE_BACK:
return true;
case KeyEvent.KEYCODE_CALL:
return true;
case KeyEvent.KEYCODE_SYM:
return true;
case KeyEvent.KEYCODE_VOLUME_DOWN:
return true;
case KeyEvent.KEYCODE_VOLUME_UP:
return true;
case KeyEvent.KEYCODE_STAR:
return true;
}
屏蔽home键后全屏消失,www.zzzyk.com 说明你是在代码中设置全屏的,转到AndroidManifest.xml设置全屏就行
<activity android:name=".WelcomeActivity" android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
