Scrollview嵌套webview，解决webview高度无

一、xml佈局中，webview設置一个高度

<androidx.core.widget.NestedScrollView
            android:id="@+id/nestedScrollView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="none"
           >
                <WebView
                    android:id="@+id/webView"
                    android:layout_width="match_parent"
                    android:layout_height="100dp"
                    android:layout_marginStart="15dp"
                    android:layout_marginEnd="15dp"
                    android:scrollbars="none" />

</androidx.core.widget.NestedScrollView>

二、在onPageFinished中重新给webview设置宽和高

webView.setOnPageFinishListener(() -> {
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                          webView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,       
                                                                 LinearLayout.LayoutParams.WRAP_CONTENT));
                    }
                });
