Webview小结，方便新手直接上手

简单介绍下webview可以直接复制到项目中使用。

1、

界面布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <WebView        android:id="@+id/thirdpartwebview"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="@color/white"        android:scrollbars="none" /></LinearLayout>

2、

代码及介绍

public class ThirdPartyWebView1 extends MainNoBackBaseActivity {    @BindView(R.id.thirdpartwebview)    WebView thirdpartwebview;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.third_part_webview);    }    @Override    public void initView() {        thirdpartwebview.setWebChromeClient(new WebChromeClient());        thirdpartwebview.getSettings().setDefaultTextEncodingName("utf-8");// 避免中文乱码         thirdpartwebview.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);        WebSettings settings = thirdpartwebview.getSettings();        settings.setJavaScriptEnabled(true);        settings.setNeedInitialFocus(false);        settings.setSupportZoom(true);        settings.setAppCacheEnabled(true);  //开启缓存功能        settings.setCacheMode(WebSettings.LOAD_DEFAULT);        settings.setLoadWithOverviewMode(true);//适应屏幕        settings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);        settings.setLoadsImagesAutomatically(true);//自动加载图片        settings.setDomStorageEnabled(true);//这里你酌情看看要不要加这句代码，两年代码就遇到一次需要加的，因为界面加载不出来，加了这句话才加载出来的。也是因为要加这句才写这篇博客的。        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {            settings.setMixedContentMode(thirdpartwebview.getSettings().MIXED_CONTENT_ALWAYS_ALLOW);  //注意安卓5.0以上的权限        }        
       // 封装监听home键        mHomeWatcher = new HomeWatcher(this);        mHomeWatcher.setOnHomePressedListener(new HomeWatcher.OnHomePressedListener() {            @Override            public void onHomePressed() {                thirdpartwebview.onPause();            }            @Override            public void onHomeLongPressed() {            }        });        mHomeWatcher.startWatch();    }    @Override    public void initData() {        thirdpartwebview.loadUrl(spreadUrl);        thirdpartwebview.setWebViewClient(new WebViewClient() {            @Override            public boolean shouldOverrideUrlLoading(WebView view, String url) {                if(url.endsWith(".apk")){                    CLToastUtil.showToast(ThirdPartyWebView1.this,"需要去下载apk");                }else{                    view.loadUrl(url);                }                return false;            }            @Override            public void onPageStarted(WebView view, String url, Bitmap favicon) {                super.onPageStarted(view, url, favicon);            }            @Override            public void onPageFinished(WebView view, String url) {                super.onPageFinished(view, url);            }            @Override            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {                super.onReceivedError(view, errorCode, description, failingUrl);            }            @Override            public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {            }        });    }    //重写返回键被点击的事件    @OnClick(R.id.left_arrow)    public void OnClick(View view) {        switch (view.getId()) {            case R.id.left_arrow:                backPress();                break;        }    }    @Override    public boolean onKeyDown(int keyCode, KeyEvent event) {        // 按下键盘上按钮        if (keyCode == KeyEvent.KEYCODE_BACK) {            backPress();            return true;        } else {            return super.onKeyDown(keyCode, event);        }    }    @Override    public void onDestroy() {        mHomeWatcher.stopWatch();        super.onDestroy();    }}
