API 详解

动态添加webView,防止内存泄漏

.setWebParent(frameLayout, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT))

内存泄漏不用担心，已经在内部处理了
    @Override
    public void destroy() {
        removeAllViewsInLayout();
        ViewParent parent = getParent();
        if (parent instanceof ViewGroup) {//从父容器中移除webview
            ((ViewGroup) parent).removeAllViewsInLayout();
        }
        releaseConfigCallback();
        super.destroy();
    }

动态切换 X5和Android 的webview

如果要是用x5的webview需要在application中调用此方法 PrimWeb.init(this); 初始化x5

//使用库中X5的webview
.setWebViewType(PrimWeb.WebViewType.X5)

//使用库中Android的webview
.setWebViewType(PrimWeb.WebViewType.Android)

public enum WebViewType {
       Android, X5
}

Javascript调Java? 可以addJavascriptInterface 多个,具体请看 SafeJsInterface

primWeb.getJsInterface().addJavaObject(new MyJavaObject(),"jsAgent")

/** 注入js脚本 */
public class MyJavaObject {

        @JavascriptInterface
        public void login(String data) {

        }

    }

Java调用Javascript方法,方便安全的加载js方法可传多个参数，具体请看 SafeCallJsLoaderImpl

primWeb.getCallJsLoader().callJS("jsMethod");
primWeb.getCallJsLoader().callJS("callByAndroidParam", 1234);
primWeb.getCallJsLoader().callJs("callByAndroidMoreParams", agentValueCallback, getJson(), "prim", true);


//可传多个参数，可使用高级的API
@RequiresApi(Build.VERSION_CODES.KITKAT)
void callJs(String method, AgentValueCallback<String> callback, String... params);
@RequiresApi(Build.VERSION_CODES.KITKAT)
void callJs(String method, AgentValueCallback<String> callback);
void callJS(String method, String... params);
void callJS(String method);

灵活的设置WebSetting如：X5DefaultWebSetting 继承 BaseAgentWebSetting类注意WebSettings 是X5 的 API

.setAgentWebSetting(new X5DefaultWebSetting(this))

public class X5DefaultWebSetting extends BaseAgentWebSetting<WebSettings> {
    private Context context;
    private static final String APP_CACAHE_DIRNAME = "/webcache";

    public X5DefaultWebSetting(Context context) {
        this.context = context;
    }

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void toSetting(WebSettings webSetting) {
        webSetting.setJavaScriptEnabled(true);
        webSetting.setJavaScriptCanOpenWindowsAutomatically(true);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            // 通过 file url 加载的 Javascript 读取其他的本地文件 .建议关闭
            webSetting.setAllowFileAccessFromFileURLs(false);
            // 允许通过 file url 加载的 Javascript 可以访问其他的源，包括其他的文件和 http，https 等其他的源
            webSetting.setAllowUniversalAccessFromFileURLs(false);
        }
        }
       ......
   }

设置 setWebViewClient 使用代理的WebViewClient 兼容android webview 和 x5 webview

.setAgentWebViewClient(agentWebViewClient)

AgentWebViewClient agentWebViewClient = new AgentWebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(IAgentWebView view, String url) {
            Log.e(TAG, "shouldOverrideUrlLoading: " + url);
            return super.shouldOverrideUrlLoading(view, url);
        }

        @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
        @Override
        public boolean shouldOverrideUrlLoading(IAgentWebView view, WebResourceRequest request) {
            Log.e(TAG, "shouldOverrideUrlLoading: WebResourceRequest -->　" + request.getUrl());
            return super.shouldOverrideUrlLoading(view, request);
        }
};

代理WebChormeClient 兼容android webview 和 x5 webview

 .setAgentWebChromeClient(agentChromeClient)

AgentChromeClient agentChromeClient = new AgentChromeClient() {
        @Override
        public void onReceivedTitle(View webView, String s) {
            super.onReceivedTitle(webView, s);
            if (actionBar != null) {
                actionBar.setTitle(s);
            }
        }
    };

设置进度指示器

如果想改变指示器的颜色可以调用如下:
.useDefaultTopIndicator(@ColorInt int color)
.useDefaultTopIndicator(@NonNull String color)

如果想改变指示器的高可以调用如下:
.useDefaultTopIndicator(@ColorInt int color, int height)

如果想自定义指示器可以调用如下:主要需要继承BaseIndicatorView
.useCustomTopIndicator(@NonNull BaseIndicatorView indicatorView)

设置错误页面

不设置
.useDefaultUI()

可以设置布局的layout和点击的id
.useCustomUI(@LayoutRes int errorLayout, @IdRes int errorClickId)

可以设置为一个view
.useCustomUI(@NonNull View errorView)

灵活安全的加载url,具体可以看UrlLoader

 primWeb.getUrlLoader().loadUrl();
 primWeb.getUrlLoader().reload();
 primWeb.getUrlLoader().stopLoading();

webview的生命周期

    @Override
    protected void onResume() {
        super.onResume();
        primWeb.webLifeCycle().onResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        primWeb.webLifeCycle().onPause();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        primWeb.webLifeCycle().onDestory();
    }

判断js方法是否存在

     //设置监听
    .setListenerCheckJsFunction(this)

    //要检查的js方法
    primWeb.getCallJsLoader().checkJsMethod("returnBackHandles");

    @Override
    public void jsFunExit(Object data) {
        Toast.makeText(getActivity(), data.toString() + "方法存在", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void jsFunNoExit(Object data) {
        Toast.makeText(getActivity(), data.toString() + "方法不存在", Toast.LENGTH_SHORT).show();
    }

内部是这样处理的,我自己写了一个js方法，来专门判断, 具体请看BaseCallJsLoader

 @Override
    public void checkJsMethod(String method) {
        StringBuilder sb = new StringBuilder();
        sb.append("function checkJsFunction(){ if(typeof ")
                .append(method)
                .append(" != \"undefined\" && typeof ")
                .append(method)
                .append(" == \"function\")")
                .append("{console.log(\"")
                .append(method)
                .append("\");")
                .append("checkJsBridge['jsFunctionExit']();")
                .append("}else{")
                .append("if(typeof checkJsBridge == \"undefined\") return false;")
                .append("checkJsBridge['jsFunctionNo']();}}");
        call("javascript:" + sb.toString() + ";checkJsFunction()", null);
    }

webview 上传文件

PrimWeb库已经默认实现了文件上传

如果想禁止文件上传可以设置:
.setAllowUploadFile(false)

如果想使用第三方文件选择库上传文件设置:
.setUpdateInvokThrid(true)

同时具体的上传逻辑需要自己完成,具体的可以看Demo


@Override
    public void jsOpenVideos() {
        Log.e(TAG, "jsOpenVideos: ");
        PrimPicker.with(WebFragment.this)
                .choose(MimeType.ofVideo())
                .setMaxSelected(1)
                .setImageLoader(new MyImageLoad())
                .setShowSingleMediaType(true)
                .setCapture(false)
                .setSpanCount(3)
                .lastGo(1001);
    }

    @Override
    public void jsOpenPick() {
        PrimPicker.with(WebFragment.this)
                .choose(MimeType.ofImage())
                .setMaxSelected(1)
                .setImageLoader(new MyImageLoad())
                .setShowSingleMediaType(true)
                .setCapture(false)
                .setSpanCount(3)
                .lastGo(1001);
    }

      private ValueCallback<Uri[]> agentValueCallbacks;

    private ValueCallback<Uri> agentValueCallback;

    AgentChromeClient agentChromeClient = new AgentChromeClient() {
        @Override
        public boolean onShowFileChooser(View webView, ValueCallback<Uri[]> valueCallback, com.tencent.smtt.sdk.WebChromeClient.FileChooserParams fileChooserParams) {
            agentValueCallbacks = valueCallback;
            //注意监听需要写在这里 否则监听有时候会收不到
            primWeb.setThriedChooserListener(WebFragment.this);
            return super.onShowFileChooser(webView, valueCallback, fileChooserParams);
        }

        @Override
        public void openFileChooser(ValueCallback<Uri> valueCallback) {
            agentValueCallback = valueCallback;
            primWeb.setThriedChooserListener(WebFragment.this);
            super.openFileChooser(valueCallback);
        }

        @Override
        public void openFileChooser(ValueCallback<Uri> valueCallback, String acceptType) {
            agentValueCallback = valueCallback;
            primWeb.setThriedChooserListener(WebFragment.this);
            super.openFileChooser(valueCallback, acceptType);
        }

        @Override
        public void openFileChooser(ValueCallback<Uri> valueCallback, String acceptType, String capture) {
            agentValueCallback = valueCallback;
            primWeb.setThriedChooserListener(WebFragment.this);
            super.openFileChooser(valueCallback, acceptType, capture);
        }
    };

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.e(TAG, "onActivityResult: requestCode --> " + requestCode + " | resultCode --> " + resultCode);
        if (resultCode == RESULT_CANCELED && requestCode == 1001) {
            cancelFilePathCallback();
        } else if (resultCode == RESULT_OK && requestCode == 1001) {
            uploadImgVideo(PrimPicker.obtainUriResult(data).get(0));
        }
    }

    private void uploadImgVideo(Uri uri) {
        Uri result = uri;
        Uri[] results = new Uri[]{uri};
        if (agentValueCallbacks != null) {
            agentValueCallbacks.onReceiveValue(results);
            agentValueCallbacks = null;
        } else if (agentValueCallback != null) {
            if (result == null) {
                return;
            }
            agentValueCallback.onReceiveValue(result);
            agentValueCallback = null;
        }
    }

    private void cancelFilePathCallback() {
        if (agentValueCallback != null) {
            agentValueCallback.onReceiveValue(null);
            agentValueCallback = null;
        } else if (agentValueCallbacks != null) {
            agentValueCallbacks.onReceiveValue(null);
            agentValueCallbacks = null;
        }
    }

回退的处理简化

返回键的回退简化:
 @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (primWeb.handlerKeyEvent(keyCode, event)) {
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }


 返回按钮的回退简化:
if (!primWeb.handlerBack()) {
                    this.finish();
                }
