Question

我必须删除“THDC”＆amp;启动画面中的“图标”和操作栏中的主屏幕。请看侧边菜单的图像＆amp;启动画面。我在下面附上代码。如何从启动画面中删除切换侧面菜单按钮。请帮我删除。

MainActivity.java

public class MainActivity extends Activity {

    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ActionBarDrawerToggle mDrawerToggle;

    //  drawer title

                </intent-filter>

            </activity>

在style.xml中添加样式

<style name="myStyle" parent="Theme.AppCompat.Light.NoActionBar">

    </style>

Answer 2

将onCreate()修改为以下内容：

assert getSupportActionBar() != null;
getSupportActionBar().hide();
setContentView(R.layout.activity_splash);

View mContentView = findViewById(R.id.fullscreen_content);
mContentView.setSystemUiVisibility(View.GONE | View.SYSTEM_UI_FLAG_FULLSCREEN);

其中fullscreen_content是您父布局的ID。

例如。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/fullscreen_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@mipmap/ic_splash_bk"
    tools:context="com.abc.xyz.Splash">

    // content of splash

</RelativeLayout>

Answer 3

代码执行的顺序可能有问题。

<强> SplashActivity.java

public class SplashActivity extends AppCompactActivity {

    protected int _splashTime = 2000;
    int secondsDelayed = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    

        assert getSupportActionBar() != null;
        getSupportActionBar().hide();
        setContentView(R.layout.activity_splash);
        mContentView = findViewById(R.id.fullscreen_content);
        mContentView.setSystemUiVisibility(View.GONE | View.SYSTEM_UI_FLAG_FULLSCREEN);

        new Handler().postDelayed(new Runnable() {
            public void run() {
                Intent HomeScreen = new Intent(getApplicationContext(), MainActivity.class);
                startActivity(HomeScreen);
                overridePendingTransition(0, 0);
                finish();
            }
        }, secondsDelayed * _splashTime);

    }

}

AndroidManifest.xml

<activity
android:name="com.abc.xyz.SplashActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@style/FullscreenTheme" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />  
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
