Question

我有一个大约十五个按钮的屏幕。每个按钮应该在另一个屏幕（设置为活动）的webview中打开特定URL。如何根据点击的按钮使webview显示正确的URL？

这是我的按钮代码：

 }

@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub

}

}

以下是包含webview的活动的代码：

package com.adanawtn.FunnMagViewerWindow;

import com.adanawtn.funnmagviewerwindow.R;


import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.webkit.WebView;

public class Class1 extends Activity {

 @Override

    protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_class1);


 WebView webview1 = (WebView) findViewById(R.id.webView1);


Intent logoClick = getIntent();
    String uri = logoClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(uri);

Intent twitClick = getIntent();
    String twituri = twitClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(twituri);   


Intent instClick = getIntent();
    String insturi = instClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(insturi);  

    Intent bestClick = getIntent();
    String besturi = bestClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(besturi);  

    Intent gearsClick = getIntent();
    String gearsuri = gearsClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(gearsuri);     

 Intent artsClick = getIntent();
    String artsuri = artsClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(artsuri);  

    Intent travelClick = getIntent();
    String traveluri = travelClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(traveluri);    

 Intent eventsClick = getIntent();
    String eventsuri = eventsClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(eventsuri); 

 Intent dailyClick = getIntent();
    String dailyuri = dailyClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(dailyuri);     

 Intent magClick = getIntent();
    String maguri = magClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(maguri);   

    Intent tvClick = getIntent();
    String tvuri = tvClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(tvuri);    


Intent mallClick = getIntent();
    String malluri = mallClick.getStringExtra("uri");
    setContentView(webview1);
    webview1.loadUrl(malluri);  


}


}

Answer 1

您应该像这个例子一样构建Intents：

Intent instClick = new Intent(this, Class1.class);
instClick.putExtra("uri", "http://instagram.com/funnmagazine");
startActivity(instClick);

然后，您在webview活动中的代码应该可以使用，但是您只需要使用一小部分代码来设置webview而不是全部十五个。

获取按钮以在webview中打开不同的URL
