# Android WebViewJavascriptBridge
#### gradle script for jsbridge.jar
```bash
./gradlew :jsbridge:publish
```
> 生成的jar包和js文件位于jsbridge/dist/目录下
### how to use
1. 复制jsbridge/dist/WebViewJavascriptBridge.js到应用目录的assets文件夹下，复制jsbridge/dist/js-bridge.jar到应用目录的libs目录下；
2. 在应用的build.gradle文件中添加依赖
```
dependencies {
...
compile files('libs/jsbridge-1.0.0.jar')
}
```
3. Sample Code
```java
// Code In Activity:
import com.wangdahoo.jsbridge.JSBridgeWebView;
import com.wangdahoo.jsbridge.JSBridgeWebViewClient;
import com.wangdahoo.jsbridge.MessageDispatcher;
...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 1. 创建JSBridgeWebView实例
webView = new JSBridgeWebView(this);
// 2. 创建MessageDispather：消息派发组件, 拦截js端发送过来的消息，然后派发给消息中指定的消息处理组件（Handler）进行处理
MessageDispatcher messageDispatcher = new MessageDispatcher();
// 3. 给MessageDispather添加Hanlder
messageDispatcher.registerHandler("DialogAlert", new DialogAlertHandler(this));
// 4. 设置WebViewClient
webView.setWebViewClient(new JSBridgeWebViewClient(webView, messageDispatcher));
...
}
...
```
```java
// 实现MessageHanlder
public class DialogAlertHandler extends BaseMessageHandler implements MessageHandler {
String title = "提示";
String content = "";
String btnOkText = "确定";
Context context;
public DialogAlertHandler(Context context) {
this.context = context;
}
// 实现handle方法即可
@Override
public void handle(JSONObject message, final Callback callback) {
JSONObject data = getData(message);
final String callbackId = getStringValueByField(message, "callbackId");
if (data.has("title"))
title = getStringValueByField(data, "title");
if (data.has("content"))
content = getStringValueByField(data, "content");
if (data.has("btnOkText"))
btnOkText = getStringValueByField(data, "btnOkText");
AlertDialog.Builder builder = new AlertDialog.Builder(context)
.setTitle(title)
.setMessage(content)
.setPositiveButton(btnOkText, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (callback != null)
callback.onCallback(makeResponse(callbackId));
}
});
builder.create();
builder.show();
}
}
```
That's all and have fun.
