我需要一些教程级别的帮助,以定时顺序显示WebView内容。
下面只是一个测试平台来说明,清单是RelativeLayout中的沼泽标准WebView。
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.widget.RelativeLayout;
public class MyActivity extends Activity
{
private String imgPath; // empty for testing
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final WebView mWebView1;
mWebView1 = (WebView) findViewById(R.id.webviewCard1);
mWebView1.setLayoutParams(new RelativeLayout.LayoutParams(300,200));
String fill = "First Content";
mWebView1.loadDataWithBaseURL(imgPath, fill, "text/html", "utf-8",null);
/*
I want the above to load, display First Content (text, image(s), play any
sound files) then pause for a preset time before doing the same for the
Second Content
*/
fill = "Second Content";
mWebView1.loadDataWithBaseURL(imgPath, fill, "text/html", "utf-8",null);
}
}
那么如何在loadDataWithBaseURLs(在相同或不同的WebViews上)之间强制等待n秒呢?
TIA,

答案 0 :(得分:0)
怎么样: mWebView1.postDelayed(...,timeout);
或
Executors.newSingleThreadScheduledExecutor()。scheduleWithFixedDelay(command,initialDelay,delay,unit);
我认为任何计时器都可以,只需确保在UI线程上调用webview方法。
