android 中集成h5 的步骤 -- 貌似内容会比较多

访问量: 415

1. 做一个基本的hello world 出来. 

2.  要有个Base Activity 

package topgroup.com.topgroupandroid;

import android.app.ProgressDialog;
import android.content.Context;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;

import java.util.Locale;

/**
   基础类 Activity ,
   所有的Activity 都要继承它。 目的是能更好的动态切换语言。
 */
public class BaseActivity extends AppCompatActivity {

    private Locale current_locale;

    @Override
    protected void onStart(){
        super.onStart();
        current_locale = getResources().getConfiguration().locale;
    }


    @Override
    protected  void onRestart(){
        super.onRestart();
        Locale locale = getLocale(this);
        if(!locale.equals(current_locale)){
            current_locale = locale;
            recreate();
        }
    }
    public static Locale getLocale(Context content){
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(content);
        String lang = sharedPreferences.getString("language", "en");
        Log.d("== country:", lang);
        return new Locale(lang);
    }




    protected final String TAG = getClass().getSimpleName();
    private ProgressDialog loadingDialg;


    public void showLoadingDialog() {

        if (loadingDialg == null) {
            loadingDialg = new ProgressDialog(this);
            loadingDialg.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            loadingDialg.setIndeterminate(false);
            loadingDialg.setCancelable(true);
            loadingDialg.setMessage("正在加载数据");
            loadingDialg.show();
        }

    }

    public void dismissLoadingDialog() {
        if (loadingDialg != null) {
            loadingDialg.dismiss();
        }
    }
}


3. 所有的Activity 都要继承于这个  BaseActivity

package topgroup.com.topgroupandroid;

import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.util.Log;

import android.widget.TextView;

import java.util.Locale;

public class MainActivity extends BaseActivity implements View.OnClickListener{

    private RadioButton radioButton1;
    private RadioButton radioButton2;
    private RadioButton radioButton3;
    private RadioButton radioButton4;

    private ImageView searchButton;
    private TextView chooseCity;
    private TextView titleText;
    private ImageView titleImage;
    private TextView topFankui;
    private WebView webview;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 获得语言设置
        SharedPreferences settings = getSharedPreferences(Constants.REFERENCE_NAME, 0);
        String languageToLoad = settings.getString(Constants.KEY_LANGUAGE, Constants.DEFAULT_LANGUAGE);

        Locale locale = new Locale(languageToLoad);
        Locale.setDefault(locale);

        Configuration configuration = new Configuration();
        configuration.locale = locale;

        getBaseContext().getResources().updateConfiguration(
                configuration,
                getBaseContext().getResources().getDisplayMetrics()
        );

        this.setContentView(R.layout.main_activity);

        initView();

        setWebView();


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }


    public void goToSwitchLanguageActivity(View view){
        Intent intent = new Intent(this, SwitchLanguageActivity.class);
        Log.d("== ", "go to SwitchLanguageActivity");
        startActivity(intent);
        finish();
    }

    private void initView() {
        radioButton1 = (RadioButton) findViewById(R.id.button_home);
        radioButton1.setOnClickListener(this);
        radioButton2 = (RadioButton) findViewById(R.id.button_activity);
        radioButton2.setOnClickListener(this);
        radioButton3 = (RadioButton) findViewById(R.id.button_game);
        radioButton3.setOnClickListener(this);
        radioButton4 = (RadioButton) findViewById(R.id.button_me);
        radioButton4.setOnClickListener(this);

        searchButton = (ImageView) findViewById(R.id.searchButton);
        searchButton.setVisibility(View.GONE);

        chooseCity = (TextView) findViewById(R.id.chooseCity);
        chooseCity.setOnClickListener(this);
        chooseCity.setVisibility(View.VISIBLE);

        titleImage = (ImageView) findViewById(R.id.titleImage);
        titleImage.setVisibility(View.VISIBLE);

        titleText = (TextView) findViewById(R.id.titleText);
        titleText.setVisibility(View.GONE);

        topFankui = (TextView) findViewById(R.id.topFankui);
        topFankui.setOnClickListener(this);

        webview = (WebView) findViewById(R.id.homeWebView);
    }

    private void setWebView() {
        radioButton1.setChecked(true);

        webview.getSettings().setJavaScriptEnabled(true);
        webview.getSettings().setDomStorageEnabled(true);
        WebSettings settings = webview.getSettings();
        settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NORMAL);    //排版适应屏幕
        settings.setLoadWithOverviewMode(true);                             // setUseWideViewPort方法设置webview推荐使用的窗口。setL
        settings.setUseWideViewPort(true);
        settings.setPluginState(WebSettings.PluginState.ON);
        settings.setJavaScriptCanOpenWindowsAutomatically(true);
        settings.setAllowFileAccess(true);
        settings.setDefaultTextEncodingName("UTF-8");
        webview.setBackgroundColor(0);
        webview.setVisibility(View.VISIBLE);
        webview.setWebViewClient(new homeWebViewClient());
    }

    @Override
    public void onClick(View view){
        switch(view.getId()){
            case R.id.button_game:
                Intent intent = new Intent(this, GameActivity.class );
                startActivity(intent);
                finish();
                break;
        }
    }



    // 记得添加这个 WebViewClient
    public class homeWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            Log.d(TAG, "onPageFinished, 触发的url是====" + url);
            view.loadUrl(url);
            return false;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            Log.d(TAG, "onPageStarted, 触发的url是====" + url);
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
            Log.d(TAG, "shouldInterceptRequest, 触发的url是====" + url);
            return super.shouldInterceptRequest(view, url);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);

//            getUserId();
//
//            Log.d(TAG, "onPageFinished, 触发的url是====" + url);
//            Pattern pattern = Pattern.compile("product");
//            Matcher matcher = pattern.matcher(url);
//            if (matcher.find()) {
//                Log.d(TAG, "拦截到了,跳转产品详情===");
//                //跳转到产品activity
//                toProduct(url);
//            }



            Log.d(TAG, "取消小菊花开始...");
            // 取消小菊花 放在这里才可以.   针对myorder  打开的时候小菊花不会消失。
            try {
                dismissLoadingDialog();
            }catch(Exception e){
                try{
                    dismissLoadingDialog();
                }catch(Exception e2) {
                    Log.e(TAG, "== 取消小菊花出错了: " + e.toString());
                }
            }
        }
    }
}

4. 记得在这个activity 中,要有个  webviewclient的继承. (上面已经写好了)  . 

记得上面的 onPageFinished 是重点.  需要根据这个来判断 页面的跳转.

5. layout 一般长这样: (具体如何做看你们)

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/pure_white"
    android:fitsSystemWindows="true"
    android:orientation="vertical"
    tools:context="topgroup.com.topgroupandroid.MainActivity"
    android:weightSum="1">
    
    <include
        android:id="@+id/top_bar"
        layout="@layout/top_bar"
        android:layout_width="match_parent"
        android:layout_height="44dp"
        />
    
    <!-- 要有这个  webview -->
    <WebView
        android:id="@+id/homeWebView"
        android:layout_width="fill_parent"
        android:layout_height="239dp"
        android:layout_below="@+id/top_bar"
        android:layout_weight="1.01">
    </WebView>
    
    <include
        android:id="@+id/tab_bar"
        layout="@layout/tab_bar"
        android:layout_width="match_parent"
        android:layout_height="44dp"
        />
</LinearLayout>

然后,该有的   top 和 bottom 都要有.  (记得重点是bottom) 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RadioGroup
        android:id="@+id/main_tabBar"
        android:layout_width="match_parent"
        android:layout_height="44dp"
        android:background="@color/pure_white"
        android:gravity="center_vertical"
        android:orientation="horizontal"
        android:layout_below="@+id/slider">

        <RadioButton
            android:id="@+id/button_home"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="#8fff"
            android:button="@null"
            android:drawableTop="@drawable/menu1_selector"
            android:gravity="center"
            android:padding="4dp"
            android:text="首页"
            android:textColor="@color/dibu_ziti_yanse"
            android:textSize="12sp" />

        <RadioButton
            android:id="@+id/button_activity"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="@color/toumingdu_25"
            android:button="@null"
            android:drawableTop="@drawable/menu2_selector"
            android:gravity="center_horizontal"
            android:text="案例"
            android:textColor="@color/dibu_ziti_yanse"
            android:textSize="12sp"/>

        <RadioButton
            android:id="@+id/button_game"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="@color/toumingdu_25"
            android:button="@null"
            android:drawableTop="@drawable/menu4_selector"
            android:gravity="center"
            android:padding="4dp"
            android:text="Game"
            android:textColor="@color/dibu_ziti_yanse"
            android:textSize="12sp" />

        <RadioButton
            android:id="@+id/button_me"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="@color/toumingdu_25"
            android:button="@null"
            android:drawableTop="@drawable/menu5_selector"
            android:gravity="center"
            android:padding="4dp"
            android:text="Me"
            android:textColor="@color/dibu_ziti_yanse"
            android:textSize="12sp" />
    </RadioGroup>
</LinearLayout>

以上面的 game_button 为例, 我们就可以根据这个来实现跳转了.  

记得在 Activity 中, 增加 onResume 这个函数:

private String url;   // 表示当前的url.  用来时刻保存和跟踪 当前的url 
    @Override
    protected void onResume() {
        super.onResume();
        if (!webview.getUrl().equals(url)) {
            Log.d(TAG, "load url at onResume: " + url);
            webview.loadUrl(url);
        }
    }
