Question

我的应用中有一个webview。我希望webview链接（点击时）加载到另一个webview中。这是我的代码的一部分.webview1中的链接在设计浏览器中加载：

        webView1.getSettings().setJavaScriptEnabled(true);
        webView2.getSettings().setJavaScriptEnabled(true);
        WebViewClient webViewClient = new WebViewClient() {


            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                webView2.loadUrl(url);
                //webView2.requestFocus();
                return true;
            }
        };
        webView1.setWebViewClient(webViewClient);

Answer 1

您的代码是正确的。
只是为了防止在设备默认浏览器中加载链接，您应该将webview客户端设置为：

webView2.setWebViewClient(new WebViewClient());

Answer 2

如果要在其他活动中打开网址，请使用以下命令：在activity1.java上添加这个。（我使用按钮从活动转移到活动）

<强> Activity1.java

声明：

Button button;

在oncrete下面：

 button = (Button) findViewById(R.id.button1);

在Oncreate之后：

public void onClick1(View view) {
        Intent intent = new Intent(Activity1.this,Activity2.class);
        //Passing a URL to activity2
        intent.putExtra("WebAddress","http://www.techmobs.in");
        Activity1.this.startActivity(intent);
    }

Activity1.java的XML部分

<Button
                android:layout_width="100dp"
                android:layout_height="40dp"
                android:id="@+id/button1"
                android:onClick="onClick1"
                android:text="Blogging" />

<强> Activity2.java

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity2);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        //Getting the URL from activity1.java
        final String WebAddress = getIntent().getStringExtra("WebAddress");

        frameLayout = (FrameLayout) findViewById(R.id.frameprogress);
        progressBar = (ProgressBar) findViewById(R.id.progress);
        progressBar.setMax(100);

                progressBar.setProgress(progress);

                setTitle("Loading...");

                if(progress == 100){
                    frameLayout.setVisibility(View.GONE);
                    setTitle(view.getTitle());
                    urlopen = WebAddress;

                }
                super.onProgressChanged(view, progress);
            }
        });
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setVerticalScrollBarEnabled(false);
        webView.loadUrl(WebAddress);
        progressBar.setProgress(0);

    }
    //Help client class definition
    class HelpClient extends WebViewClient {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url)       {
            view.loadUrl(url);
            frameLayout.setVisibility(View.VISIBLE);
            return true;
        }
    }
    @Override

        if (item.getItemId() == android.R.id.home) {
            finish();
        }
        return true;
    }

    @Override
    public void onBackPressed() {
        if (webView.canGoBack()){
            webView.goBack();
        }
        else {
         super.onBackPressed();
        }
    }
}

Activity2.java的XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.yourpackage.Activity2">
    <FrameLayout
        android:id="@+id/frameprogress"
        android:layout_width="match_parent"
        android:background="@android:color/transparent"
        android:layout_height="3dp">
        <ProgressBar
            android:id="@+id/progress"
            android:layout_width="match_parent"
            android:layout_height="8dp"
            android:background="@android:color/transparent"
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_gravity="top"
            android:layout_marginTop="-3dp"
            android:progressDrawable="@drawable/custom_progress"
            android:progress="30"/>
    </FrameLayout>
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <WebView
        android:id="@+id/web1"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </WebView>
</RelativeLayout>
</LinearLayout>

对于自定义进度条： 将其添加到名为custom_progress.xml

的drawable上

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:id="@android:id/secondaryProgress">
            <clip>
                <shape>
                    <corners android:radius="3dip" />
                    <solid android:color="#4FC3F7" />
                </shape>
            </clip>
        </item>
        <item android:id="@android:id/progress">
            <clip>
                <shape>
                    <corners android:radius="3dip" />
                    <solid android:color="#4FC3F7" />
                </shape>
            </clip>
        </item>
    </layer-list>

我希望这会对你有所帮助。这将为您的webview带来惊人的外观更多此类访问http://www.techmobs.in
