创建 webview 控件，对其进行设置

        webView = (WebView) findViewById(R.id.webview);

        webSettings = webView.getSettings();
        webSettings.setAppCacheEnabled(true);
        webSettings.setCacheMode(webSettings.LOAD_NO_CACHE);
        webSettings.setJavaScriptEnabled(true);
        webSettings.setDomStorageEnabled(true);
        webSettings.setBuiltInZoomControls(false);
        webSettings.setLoadWithOverviewMode(true);
        webSettings.setAllowFileAccess(true);

        //处理http和https混合的问题
        if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.LOLLIPOP) {
            webSettings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
        } else {
            webSettings.setMixedContentMode(WebSettings.LOAD_NORMAL);
        }

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            // 允许javascript出错
            try {
                Method method = Class.forName("android.webkit.WebView").
                        getMethod("setWebContentsDebuggingEnabled", Boolean.TYPE);
                if (method != null) {
                    method.setAccessible(true);
                    method.invoke(null, true);
                }
            } catch (Exception e) {
                // do nothing
            }
        }

        webView.setFocusable(true);// 自选，非必要
        webView.setDrawingCacheEnabled(true); // 自选，非必要

        webView.setWebViewClient(new PQClient());
        webView.setWebChromeClient(new PQChromeClient());

通过复写 WebCh romeClient.onShowFileChooser

WebChromeClient.openFileChooser

来实现打开系统图片资源

辅助WebView处理图片上传操作【<input type=file> 文件上传标签】

@RuntimePermissions

MainActivityPermissionsDispatcher.method_xWithPermissionCheck(this);

@NeedsPermission({Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE,
        Manifest.permission.CAMERA, Manifest.permission.INTERNET})
void method_x() {
    //使用权限
    Toast.makeText(this, "已有权限", Toast.LENGTH_SHORT).show();
}
