我想禁用的Andr​​oid设备主页按钮时，我的应用程序运行。

我曾尝试以下code，但它din't帮助：

  @覆盖
    公共布尔的onkeydown（INT键code，KeyEvent的事件）{
        如果（（钥匙code == KeyEvent.KEY code_HOME））{
            Toast.makeText（这一点，你pressed home键！，
                    Toast.LENGTH_LONG）.show（）;
            返回false;
        }
        返回super.onKeyDown（键code，事件）;
    }

     @覆盖
     保护无效onNewIntent（意向意图）{
     super.onNewIntent（意向）;
     如果（Intent.ACTION_MAIN.equals（intent.getAction（）））{
     Log.i（MyLauncher，onNewIntent：Home键）;

     }
     }
 

解决方案

我觉得这可以在另一种风格，如果适合您的要求来完成。通过创建活动作为家庭活动。如果您希望禁用的主页按钮，并显示您的自定义应用程序活动作为启动时，home键是pssed $ P $。就在清单对于您希望您的启动程序活动添加这些行。

 ＆LT;活动
            机器人：名称=com.example.TempActivity
            机器人：clearTaskOnLaunch =真
            机器人：excludeFromRecents =真
            机器人：launchMode =singleTask
            机器人：screenOrientation =风景
            机器人：stateNotNeeded =真正的＆GT;
             ＆LT;意向滤光器＆gt;
                ＆lt;作用机器人：名称=android.intent.action.MAIN/＆GT;

                ＆LT;类机器人：名称=android.intent.category.HOME/＆GT;
                ＆LT;类机器人：名称=android.intent.category.DEFAULT/＆GT;

            ＆所述; /意图滤光器＆gt;
＆LT; /活性GT;
 

添加和运行应用程序之后。如果用户presses home键，机器人会问你希望你的家而发射器。然后，你需要选择你的应用程序启动器总是不只有一次。

如果你想完全禁用用户，使他不能移动到其他屏幕，然后设置主题，以全屏NoTitlebar。

i want to disable android device home button when my app runs.

i have tried following code but it din't help :

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_HOME)) {
            Toast.makeText(this, "You pressed the home button!",
                    Toast.LENGTH_LONG).show();
            return false;
        }
        return super.onKeyDown(keyCode, event);
    }

     @Override
     protected void onNewIntent(Intent intent) {
     super.onNewIntent(intent);
     if (Intent.ACTION_MAIN.equals(intent.getAction())) {
     Log.i("MyLauncher", "onNewIntent: HOME Key");

     }
     }

I think this can be done in another style if suits your requirement. By creating your activity as home activity. If you want to disable home button and show your custom application activity as launcher when home button is pressed. Just add these lines in manifest for that activity for which you want your launcher.

<activity
            android:name="com.example.TempActivity"
            android:clearTaskOnLaunch="true"
            android:excludeFromRecents="true"
            android:launchMode="singleTask"
            android:screenOrientation="landscape"
            android:stateNotNeeded="true" >
             <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.HOME" />
                <category android:name="android.intent.category.DEFAULT" />

            </intent-filter>
</activity>

After adding and run your application. if user presses the home button, Android will ask for which launcher you want your home. Then your have to select your application launcher ALWAYS not ONLY ONCE.

if you want fully disable the user, so that he cant move to another screen then set theme to fullscreen with NoTitlebar.
