Question

如何从启动屏幕中删除标题栏？

我有两个活动（“主要活动”和“初始屏幕活动性”）。我为两个活动使用了代码package com.example.acer; import android.app.Activity; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Window; import android.webkit.WebSettings; import android.webkit.WebView; import android.webkit.WebViewClient; public class MainActivity extends Activity { public WebView webView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); //remove App Title bar setContentView(R.layout.activity_main); webView=(WebView)findViewById(R.id.webView); WebSettings webSettings=webView.getSettings(); webSettings.setJavaScriptEnabled(true); webView.loadUrl("http://alkhaleej-med.com/"); webView.setWebViewClient(new WebViewClient()); } @Override public void onBackPressed(){ if(webView.canGoBack()){ webView.goBack(); }else{ super.onBackPressed(); } } }，以隐藏标题栏。因此，它已从主要活动中删除，但未从初始屏幕活动中删除。

代码如下：

MainActivity.Jave：

package com.example.acer;

public class SplashScreen extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE); //remove App Title bar
        setContentView(R.layout.activity_splash_screen);

        Thread myThread = new Thread(){
            @Override
            public void run() {
                try {
                    sleep(4000);
                    Intent intent = new Intent(getApplicationContext(),MainActivity.class);
                    startActivity(intent);
                    finish();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        };
        myThread.start();
    }
}

Answer 1

转到res-values-styles，然后将基本主题更改为NoActionBar 例如

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

您已经到了一半：

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
