activity动画
从MainActivity进入到SecondActivity,然后从SecondActivity返回到MainActivity这样一个过程中如何设置两个Activity创建和销毁的动画呢?(activity转场动画
)
SDK中Activity类里面有设置动画的方法
/**
** @param enterAnim A resource ID of the animation resource to use for
* the incoming activity. Use 0 for no animation.
* @param exitAnim A resource ID of the animation resource to use for
* the outgoing activity. Use 0 for no animation.
*/
*/
public void overridePendingTransition(int enterAnim, int exitAnim) {
try {
ActivityManager.getService().overridePendingTransition(
mToken, getPackageName(), enterAnim, exitAnim);
} catch (RemoteException e) {
}
}
-
注意
此方法的设置需要在启动新activity后也就是startActivity()之后调用
,返回(销毁)时需要在finish()
方法之后调用 -
下面介绍使用方法
overridePendingTransition(int enterAnim, int exitAnim)
参数为0时无动画- step one:首先在res/下新建anim文件夹,新家4个动画
in_from_left

- 进场(启动进入)动画设置
Intent intent = new Intent();
intent.setClass(context, clazz);
intent.putExtras(bundle);
startActivity(intent);
overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
- 出场(退出)动画设置
finish();
overridePendingTransition(R.anim.in_from_left, R.anim.out_to_right);
在实际开发中往往不需要在每个启动方法处都这样添加,一般都是写到基类中然后所有继承该基类的activity都拥有转场动画,如需修改也很方便
- 如下
BaseActivity:
public void startActivity(Class clazz, Bundle bundle) {
Intent intent = new Intent();
intent.setClass(this, clazz);
intent.putExtras(bundle);
startActivity(intent);
overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}
public void startActivity(Class clazz,) {
Intent intent=new Intent();
intent.setClass(this, clazz);
startActivity(intent);
overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}
public void startActivityForResult( Class clazz, Bundle bundle, int requestCode) {
Intent intent = new Intent();
intent.setClass(this, clazz);
intent.putExtras(bundle);
startActivityForResult(intent, requestCode);
overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}
@Override
public void onBackPressed() {
super.onBackPressed();
finish();
overridePendingTransition(R.anim.in_from_left, R.anim.out_to_right);
}
