android學習筆記轉————–屏蔽返回鍵,home鍵以及其他實體按鍵

屏蔽鍵重寫activiy的兩個方法就行

屏蔽返回鍵

public boolean onKeyDown(int keyCode, KeyEvent event) {

    switch (keyCode) {
        case KeyEvent.KEYCODE_BACK:
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

 

屏蔽home鍵和別的鍵不一樣

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

屏蔽其他實體按鍵

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鍵後全屏消失,www.aiwalls.com 說明你是在代碼中設置全屏的,轉到AndroidManifest.xml設置全屏就行

<activity android:name=".WelcomeActivity" android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
>
