综合对weex技术的学习心得，整理一个activity基类。已备后用。

1、封装ComWeexActivity

public class ComWeexActivity extends AppCompatActivity implements IWXRenderListener {


    private WXSDKInstance instance;
    protected ViewGroup mContainer;

    /**
     * 获取根视图
     * @return
     */
    public ViewGroup getmContainer() {
        if (mContainer == null) {
            mContainer = new FrameLayout(this);
        }
        return mContainer;
    }
    /**
     * 重写onCreate方法
     */
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getmContainer();
        createWxInstance();
    }

    /**
     * 重写onStart方法
     */
    @Override
    protected void onStart() {
        super.onStart();
        if (instance != null) {
            instance.onActivityStart();
        }
    }
    /**
     * 重写onResume方法
     */
    @Override
    protected void onResume() {
        super.onResume();
        if (instance != null) {
            instance.onActivityResume();
        }
    }
    /**
     * 重写onPause方法
     */
    @Override
    protected void onPause() {
        super.onPause();
        if (instance != null) {
            instance.onActivityPause();
        }
    }
    /**
     * 重写onStop方法
     */
    @Override
    protected void onStop() {
        super.onStop();
        if (instance != null) {
            instance.onActivityStop();
        }
    }
    /**
     * 重写onDestroy方法
     */
    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (instance != null) {
            instance.onActivityDestroy();
        }
       desyoryWxInstance();
    }

    /**
     * 处理权限
     * @param requestCode
     * @param permissions
     * @param grantResults
     */
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (instance != null) {
            instance.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

    /**
     * 检查应用权限
     * @param requestCode
     * @param permission
     * @param runnable
     */
    public void checkPermissions(int requestCode, String permission, Runnable runnable) {
        if (ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {
                Toast.makeText(this, "please give me the permission", Toast.LENGTH_SHORT).show();
            } else {
                ActivityCompat.requestPermissions(this, new String[]{permission}, requestCode);
            }
        } else {
            if (runnable != null) {
                runnable.run();
            }
        }
    }

    /**
     * 处理activity之间传值
     * @param requestCode
     * @param resultCode
     * @param data
     */
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (instance != null) {
            instance.onActivityResult(requestCode,resultCode,data);
        }
        super.onActivityResult(requestCode, resultCode, data);
    }

    /**
     * 创建weex对象
     */
    private void createWxInstance(){
        desyoryWxInstance();
        instance = new WXSDKInstance(this);
        instance.registerRenderListener(this);
    }

    /**
     * 回收weex对象
     */
    private void desyoryWxInstance(){
        if (instance != null) {
            instance.registerRenderListener(null);
            instance.destroy();
            instance = null;
        }
    }

    /**
     * 渲染wx js页面
     */
    public void loadWX(String url){
        if (instance == null) {
            createWxInstance();
        }
        CommonUtils.throwIfNull(mContainer, new RuntimeException("Can't render page, container is null"));
        HashMap<String, Object> options = new HashMap<>();
        instance.renderByUrl(
                "nade",
                url,
                options,
                null,
                CommonUtils.getDisplayWidth(this),
                CommonUtils.getDisplayHeight(this),
                WXRenderStrategy.APPEND_ASYNC);
    }


    @Override
    public void onViewCreated(WXSDKInstance instance, View view) {
        /**
         * 添加视图
         */
        if (mContainer != null) {
            mContainer.removeAllViews();
            mContainer.addView(view);
            setContentView(mContainer);
        }
    }

    @Override
    public void onRenderSuccess(WXSDKInstance instance, int width, int height) {
        /**
         * 渲染成功
         */
    }

    @Override
    public void onRefreshSuccess(WXSDKInstance instance, int width, int height) {
        /**
         * 刷新成功
         */
    }

    @Override
    public void onException(WXSDKInstance instance, String errCode, String msg) {
        /**
         * 异常处理
         */
    }
}

2、ComWeexActivity的使用：

public class MainActivity extends ComWeexActivity {

    String url = "";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getIntent() != null && getIntent().getData() != null) {
             url = getIntent().getData().toString();
        }else {
            url = "https://weex.com/js/index.js";
            //    url = "http://192.168.3.0:8080/dist/index.js";
        }
        if (!TextUtils.isEmpty(url)) {
            loadWX(url);
        }
    }
}

3、js文件渲染类的拦截器设置

<activity android:name=".MainActivity">
            <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="wxpage"/>
            </intent-filter>
        </activity>
