按键屏蔽
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
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 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"
>
（可解决不能同时屏蔽home/back键）
