淡入淡出动画：AlphaAnimation

（2）编写MainActivity

public class MainActivity extends Activity {    private TextView tv;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        tv=(TextView)findViewById(R.id.textView1);    }    public void doClick(View view){        switch (view.getId()) {        case R.id.button4:            //Animation a4 = AnimationUtils.loadAnimation(            //      this, R.anim.translate);            //tv.startAnimation(a4);            //使用代码定义动画效果            Animation a5=new TranslateAnimation(0, 200, 0, 200);            Button b1=(Button)findViewById(R.id.button1);            a5.setDuration(1000);            a5.setFillAfter(true);            b1.startAnimation(a5);            break;        case R.id.button3:            Animation a3 = AnimationUtils.loadAnimation(                    this, R.anim.scale);            tv.startAnimation(a3);            break;        case R.id.button2:            //加载旋转动画的配置文件执行            Animation a2 = AnimationUtils.loadAnimation(                    this, R.anim.rotate);            tv.startAnimation(a2);            break;        case R.id.button1:            //加载淡入淡出动画的配置文件执行            Animation a1 = AnimationUtils.loadAnimation(                    this, R.anim.alpha);            tv.startAnimation(a1);            break;        }    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }}
