转：android按键重写

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();
}

加权限禁止Home键  <uses-permission android:name="android.permission.DISABLE_KEYGUARD"></uses-permission>  

 

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.2cto.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"
>
