Android添加欢迎界面

显示主界面前，自定义设置欢迎界面，比较简单几行代码。

package main;

import com.example.swissarmy.R;
import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.view.Window;
import android.widget.TextView;

public class WelcomeActivity extends Activity {


	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.splash);

		PackageManager pm = getPackageManager();
		try {
			PackageInfo pi = pm.getPackageInfo("com.lyt.android", 0);
		} catch (NameNotFoundException e) {
			e.printStackTrace();
		}

		new Handler().postDelayed(new Runnable(){

			@Override
			public void run() {
				Intent intent = new Intent(WelcomeActivity.this,MainActivity.class);
				startActivity(intent);
				WelcomeActivity.this.finish();
			}
		}, 3000);

	}
}
