java我的应用程序在我更改webview大小时崩溃

Question

我创建了一个显示webview的应用程序。 当我更改WebView的大小时，我的应用程序崩溃

这是我的代码：

final WebView videoWebView = (WebView) findViewById(R.id.videoWebView);
    videoWebView.getSettings().setJavaScriptEnabled(true);
    videoWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    videoWebView.getSettings().setPluginState(PluginState.ON);
    videoWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(30, 30);
    videoWebView.setLayoutParams(layoutParams);

（这个网络视图隐藏在应用程序的开头，当我显示给他时，应用程序崩溃了） 你能帮我吗

非常感谢

Answer 1

试试这个

ViewGroup.LayoutParams newParams=videoWebView.getLayoutParams();
        newParams.height=30;
        newParams.width=30;
        videoWebView.setLayoutParams(newParams);

还是这个

FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(30, 30); 
videoWebView.setLayoutParams(layoutParams);

Answer 2

将代码中的LinearLayout.LayoutParams替换为FrameLayout.LayoutParams：

 LinearLayout.LayoutParams layoutParams =  LinearLayout.LayoutParams(30, 30);

与：

FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(30, 30);
