android動畫初級入門

   Android中的動畫處理能夠用SurfaceView來處理，研究深的同窗們能夠作一些遊戲什麼的好玩的東西，對於淺淺的咱們也只是平面的樣子了下面直接說一下簡單的動畫的四種變換方式：

旋轉、移動、縮放、淡入淡出，示例以下

public class MainActivity extends Activity {
    private ImageView iv;
                 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv = (ImageView) findViewById(R.id.p_w_picpathView1);
        iv.setOnClickListener(new OnClickListener() {
                         
            @Override
            public void onClick(View v) {
                AnimationSet animationSet = new AnimationSet(true);
                AlphaAnimation alpha = new AlphaAnimation(1, 0);
                alpha.setDuration(4000);
                animationSet.addAnimation(alpha);
                iv.setBackgroundResource(R.drawable.i7);
                iv.startAnimation(animationSet);
            }
        });
    }
                 
}
public class MainActivity extends Activity {
    private ImageView iv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv = (ImageView) findViewById(R.id.p_w_picpathView1);
        iv.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                AnimationSet animationSet = new AnimationSet(false);
                RotateAnimation rotate = new RotateAnimation(0, 360,
                        Animation.RELATIVE_TO_SELF, 0.5f,
                        Animation.RELATIVE_TO_SELF, 0.5f);
                rotate.setDuration(2000);
                animationSet.addAnimation(rotate);
                iv.startAnimation(animationSet);
            }
        });
    }
}
public class MainActivity extends Activity {
    private ImageView iv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv = (ImageView) findViewById(R.id.p_w_picpathView1);
        iv.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                AnimationSet animationSet = new AnimationSet(true);
                ScaleAnimation scale = new ScaleAnimation(1, 0.25f, 1, 0.25f,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
                scale.setDuration(3000);
                animationSet.addAnimation(scale);
//              iv.setBackgroundColor(color.black);
                iv.startAnimation(scale);
            }
        });
    }
}
public class MainActivity extends Activity {
                 
    private ImageView iv;
                 
    @Override

                AnimationSet animationSet = new AnimationSet(false);
                TranslateAnimation translate  = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 1, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 1);

            public void onAnimationStart(Animation animation) {
            }
                         
            @Override
            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub
                             
            }

        });
    }

效果請在模擬器中觀察哈~
