编写App的开场Activity

 在android的app和游戏的应用中，都会有个开场场景，老外管这个叫splash。
现在就编写个简单的SplashActivity

Java代码

1. import android.app.Activity;
2. import android.content.Intent;
3. import android.os.Bundle;
4. import android.widget.ImageView;
5.  
6. public class SplashActivity extends Activity {
7.  
8. @Override
9. protected void onCreate(Bundle savedInstanceState) {
10. super.onCreate(savedInstanceState);
11. setContentView(R.layout.splash);
12.  
13. ImageView splashImg = (ImageView) findViewById(R.id.splash_p_w_picpath);
14. splashImg.postDelayed(new Runnable() {//这里利用了View的postDelayed
15.  
16. public void run() {
17. Intent intent = new Intent();
18. intent.setClass(SplashActivity.this, MainActivity.class);
19. startActivity(intent);
20. finish();
21. }
22. }, 1000);
23. }
24. }

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ImageView;

public class SplashActivity extends Activity {

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

		ImageView splashImg = (ImageView) findViewById(R.id.splash_p_w_picpath);
		splashImg.postDelayed(new Runnable() {//这里利用了View的postDelayed

			public void run() {
				Intent intent = new Intent();
				intent.setClass(SplashActivity.this, MainActivity.class);
				startActivity(intent);
				finish();
			}
		}, 1000);
	}
}
