我正在开发一个 webview 应用程序,我的问题是左右两侧都有空白,我是初学者,我不知道如何删除它们,请帮忙。 注意:请在您的答案中具体说明,例如:在名为布局的 java 框中的全屏内容中添加此代码。
非常感谢,这是代码: 1-布局-全屏 Activity 文件夹
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fullscreen);
WebView view = (WebView) this.findViewById(R.id.webView);
view.setWebViewClient(new WebViewClient());
view.loadUrl("http://google.com");
view.getSettings().setJavaScriptEnabled(true);
mVisible = true;
mControlsView = findViewById(R.id.webView);
mContentView = findViewById(R.id.webView);
// Set up the user interaction to manually show or hide the system UI.
mContentView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
toggle();
}
});
// Upon interacting with UI controls, delay any scheduled hide()
// operations to prevent the jarring behavior of controls going away
// while interacting with the UI.
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Trigger the initial hide() shortly after the activity has been
// created, to briefly hint to the user that UI controls
// are available.
delayedHide(100);
}
private void toggle() {
if (mVisible) {
hide();
} else {
show();
}
}
private void hide() {
// Hide UI first
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.hide();
}
mControlsView.setVisibility(View.GONE);
mVisible = false;

最佳答案
我发现了问题,只是添加了这段代码,webview 适合全屏。
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setLoadWithOverviewMode(true);
