篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了获取按钮以在webview中打开不同的URL相关的知识,希望对你有一定的参考价值。
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。如何根据单击的按钮使webview显示正确的URL?
这是我的按钮代码:
package com.adanawtn.FunnMagViewerWindow;
import com.adanawtn.funnmagviewerwindow.R;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class mainactivity extends Activity implements OnClickListener
{
Button logobtn;
Button twitterbtn;
Button instagrambtn;
Button topeyebtn;
Button bestbtn;
Button gearsbtn;
Button artsbtn;
Button travelbtn;
Button eventsbtn;
Button dailybtn;
Button magbtn;
Button bttmeyebtn;
Button tvbtn;
Button mallbtn;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start);
Button twitterbtn = (Button) findViewById(R.id.twitterbtn);
Button instagrambtn = (Button) findViewById(R.id.instagrambtn);
Button topeyebtn = (Button) findViewById(R.id.topeyebtn);
Button bestbtn = (Button) findViewById(R.id.bestbtn);
Button gearsbtn = (Button) findViewById(R.id.gearsbtn);
Button artsbtn = (Button) findViewById(R.id.artsbtn);
Button travelbtn = (Button) findViewById(R.id.travelbtn);
Button eventsbtn = (Button) findViewById(R.id.eventsbtn);
Button dailybtn = (Button) findViewById(R.id.dailybtn);
Button magbtn = (Button) findViewById(R.id.magbtn);
Button bttmeyebtn = (Button) findViewById(R.id.bttmeyebtn);
Button tvbtn = (Button) findViewById(R.id.tvbtn);
Button mallbtn = (Button) findViewById(R.id.mallbtn);
// logo
logobtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {

startActivity(logoClick);
}});
// twitter

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);
}
}
答案
你应该像这个例子一样构建你的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工作,但是您只需要用于设置webview而不是全部15个代码的一小部分代码。
