我正在尝试隐藏我的应用的标题栏但是如果我尝试添加以下代码&发射时立即停止&显示不幸的应用程序(应用程序名称)已停止如果我从代码中删除以下行,则它可以正常工作。
以下代码我正在使用onCreate()方法
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
我只想隐藏标题栏。代码
有什么问题吗?protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://google.com");
}

您必须在requestWindowFeature
setContentView()
像这样:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://google.com");
}

试试这个,
在您的' MainActivity.java'
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView.loadUrl("http://www.cnn.com");
}
}
并在android manifest
选择/设置主题为NoTitleBar
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/Theme.AppCompat.NoActionBar">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"></action>
<category android:name="android.intent.category.LAUNCHER"></category>
</intent-filter>
</activity>
</application>

查看错误堆栈跟踪:
引起:android.util.AndroidRuntimeException:在添加内容之前必须调用requestFeature()
您必须在setContentView()
之前调用requestWindowFeature所以您的问题是代码的以下行
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
之前需要调用它
setContentView(R.layout.activity_main);
这样说:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://google.com");
}
