我正在尝试建立我的第一个应用程序,它只是。启动->SplashScreen->自动显示网页(全屏/无按钮触发)。但是,在溅屏之后,它只是一片空白。我猜mainactivity.java中的Intent
部分和androidmanifest.xml中的intent-filter
部分有问题。但我还不知道该怎么办。
这是我的代码:
main活动.java
package com.myapp.splashscreen;
import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(context, WebViewActivity.class);
startActivity(intent);
}
}
splashscreen.java网站
package com.myapp.splashscreen;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
public class SplashScreen extends Activity {
private static final int SPLASH_TIME = 3 * 1000;// 3 seconds
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent intent = new Intent(SplashScreen.this,
MainActivity.class);
startActivity(intent);
SplashScreen.this.finish();
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
}
}, SPLASH_TIME);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
}
}, SPLASH_TIME);
}
@Override
public void onBackPressed() {
this.finish();
super.onBackPressed();
}
}
webviewactivity.java
package com.myapp.splashscreen;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WebViewActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.id.webView1);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
}
}

最佳答案
如果您想要splashActivity->webviewActivity
飞溅活动的变化
Intent intent = new Intent(SplashScreen.this,
MainActivity.class);
到
Intent intent = new Intent(SplashScreen.this,
WebViewActivity.class);
这将告诉应用程序应该启动webviewactivity而不是mainactivity
