1.首先在res下新建activity的UI文件

2.对应的界面逻辑代码

package com.game.test;import android.app.Activity;import android.webkit.WebResourceRequest;import android.webkit.WebSettings;import android.webkit.WebViewClient;import android.widget.Button;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.webkit.WebView;import android.widget.ImageButton;public class WebViewActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_web_view_layer);        WebView webView = (WebView) findViewById(R.id.webView);        String url = "http://www.csdn.net";        webView.loadUrl(url);        WebSettings webSettings = webView.getSettings();        webSettings.setJavaScriptEnabled(true);// 支持JavaScript        webSettings.setSupportZoom(true);// 支持缩放        webSettings.setBuiltInZoomControls(true);        // 如果不设置WebViewClient 那么会调用系统的浏览器        webView.setWebViewClient(new WebViewClient() {            @Override            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {                // AndroidStudio 提示Override方法快捷键 Alt+Insert                return super.shouldOverrideUrlLoading(view, request);            }        });        // 关闭网页按钮        Button btn = (Button) findViewById(R.id.button);        btn.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                finish();            }        });        ImageButton imageButton = (ImageButton) findViewById(R.id.imgBtn);        imageButton.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                finish();            }        });    }}
