Weex 初体验(2)-navigator android跳转

1.Weex代码

var navigator = weex.requireModule('navigator')
navigator.push({
    url:‘file://assets/dist/page/test.js‘
    animated: "true"
}, event => {})

Url：就是你的android目录的想要加载JS的路径。

2.Android相关代码

• 创建一个Activity，如下图所示位置以及代码

  

package com.weex.app.util;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;

import com.taobao.weex.IWXRenderListener;
import com.taobao.weex.WXSDKInstance;
import com.taobao.weex.common.WXRenderStrategy;
import com.taobao.weex.devtools.common.LogUtil;
import com.weex.app.R;

import java.util.HashMap;
import java.util.Map;

public class Network extends AppCompatActivity implements IWXRenderListener {

    private WXSDKInstance mWXSDKInstance;
    private FrameLayout mContainer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_network);

        mContainer = (FrameLayout) findViewById(R.id.container);

        mWXSDKInstance = new WXSDKInstance(this);
        mWXSDKInstance.registerRenderListener(this);

        String RenderPageUrl = "";
        if (getIntent().getData() != null) {
            String navUrl = getIntent().getData().toString();
            if (null != navUrl) {
                LogUtil.e(navUrl);
                RenderPageUrl = navUrl;
            } else {
                LogUtil.e("a is null");
            }
        } else {
            LogUtil.e("get data is null");
        }
        Map<String, Object> options = new HashMap<>();
        options.put(WXSDKInstance.BUNDLE_URL, RenderPageUrl);
        mWXSDKInstance.renderByUrl("WXSample", RenderPageUrl, options, null, WXRenderStrategy.APPEND_ONCE);
    }

    @Override
    protected void onStart() {
        super.onStart();
        if (mWXSDKInstance != null) {
            mWXSDKInstance.onActivityStart();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (mWXSDKInstance != null) {
            mWXSDKInstance.onActivityResume();
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        if (mWXSDKInstance != null) {
            mWXSDKInstance.onActivityPause();
        }
    }

    @Override
    protected void onStop() {
        super.onStop();
        if (mWXSDKInstance != null) {
            mWXSDKInstance.onActivityStop();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mWXSDKInstance != null) {
            mWXSDKInstance.onActivityDestroy();
        }
    }

    @Override
    public void onViewCreated(WXSDKInstance instance, View view) {
        if (view.getParent() != null) {
            ((ViewGroup) view.getParent()).removeView(view);
        }
        mContainer.addView(view);
    }

    @Override
    public void onRenderSuccess(WXSDKInstance instance, int width, int height) {

    }

    @Override
    public void onRefreshSuccess(WXSDKInstance instance, int width, int height) {

    }

    @Override
    public void onException(WXSDKInstance instance, String errCode, String msg) {

    }
}

• 创建Activity布局文件
  

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_network"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"></FrameLayout>

</RelativeLayout>

• 修改manifest.xml-添加拦截器

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          package="com.weex.app">

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.CAMERA"/>
    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/>

    <uses-feature android:name="android.hardware.camera"/>
    <uses-feature android:name="android.hardware.camera.autofocus"/>

    <application
        android:name="com.weex.app.WXApplication"
        android:allowBackup="false"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:overrideLibrary="com.taobao.android.dexposed"
        tools:replace="android:allowBackup">
        <activity
            android:name="com.weex.app.SplashActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:label="@string/app_name"
            android:screenOrientation="portrait"
            android:theme="@style/FullscreenTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity
            android:name="com.weex.app.WXPageActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait">
        </activity>

        <activity android:name=".util.Network">
        <intent-filter>
            <action android:name="com.taobao.android.intent.action.WEEX" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="com.taobao.android.intent.category.WEEX" />
            <action android:name="android.intent.action.VIEW" />
            <data android:scheme="http" />
            <data android:scheme="https" />
            <data android:scheme="file" />
            <data android:scheme="network" />
        </intent-filter>
    </activity>

        <activity
            android:name="com.journeyapps.barcodescanner.CaptureActivity"
            android:screenOrientation="portrait"
            tools:replace="screenOrientation"/>
    </application>

</manifest>

3.介绍

原理就是创建一个新的Activity ，利用拦截器通过隐式跳转到Network Activity，然后调用Weex API 进行JS渲染。
