[Android]直向、橫向的設定

問題：
Android 螢幕的直向？橫向？




一、程式碼

Activity.java

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); //強置為橫向
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); //強置為直向
        

[Android] 動畫的實現

一、程式碼

Activity.java

package tw.G000E004;

import android.app.Activity;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;

public class G000E004Activity extends Activity {
    Animation myanimation;
    ImageView img;
	
	/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        myanimation=AnimationUtils.loadAnimation(this, R.anim.myanim);
        img=(ImageView)findViewById(R.id.img);
        
        img.startAnimation(myanimation);
    }
}
