zzz40500/AndroidSweetSheet: 一个富有动感的Sheet(选择器)
效果如下
示例代码
package com.zj.testsheet;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.RelativeLayout;
import android.widget.Toast;
import com.mingle.entity.MenuEntity;
import com.mingle.sweetpick.BlurEffect;
import com.mingle.sweetpick.RecyclerViewDelegate;
import com.mingle.sweetpick.SweetSheet;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
SweetSheet mSweetSheet;
RelativeLayout rl;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rl= (RelativeLayout) findViewById(R.id.rl);
// SweetSheet 控件,根据 rl 确认位置
mSweetSheet = new SweetSheet(rl);
final ArrayList<MenuEntity> list = new ArrayList<>();
//添加假数据
MenuEntity menuEntity1 = new MenuEntity();
menuEntity1.iconId = R.drawable.ic_account_child;
//menuEntity1.titleColor = 0xff000000;
menuEntity1.title = "code";
MenuEntity menuEntity = new MenuEntity();
menuEntity.iconId = R.drawable.ic_account_child;
//menuEntity.titleColor = 0xffb3b3b3;
menuEntity.title = "QQ";
list.add(menuEntity1);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
list.add(menuEntity);
//设置数据源 (数据源支持设置 list 数组,也支持从menu 资源中获取)
mSweetSheet.setMenuList(list);
SweetSheet mSweetSheet2 = new SweetSheet(rl);
//从menu 中设置数据源
mSweetSheet2.setMenuList(R.menu.menu_sweet);
//根据设置不同的 Delegate 来显示不同的风格.
mSweetSheet.setDelegate(new RecyclerViewDelegate(true));
//根据设置不同Effect来设置背景效果:BlurEffect 模糊效果.DimEffect 变暗效果,NoneEffect 没有效果.
mSweetSheet.setBackgroundEffect(new BlurEffect(8));
//设置菜单点击事件
mSweetSheet.setOnMenuItemClickListener(new SweetSheet.OnMenuItemClickListener() {
@Override
public boolean onItemClick(int position, MenuEntity menuEntity1) {
//根据返回值, true 会关闭 SweetSheet ,false 则不会.
Toast.makeText(MainActivity.this, menuEntity1.title + " " + position, Toast.LENGTH_SHORT).show();
return true;
}
});
mSweetSheet.show();
}
}
A fluent Android animation library。安卓动画库
主要包括一些进度条效果

效果如下
示例代码
private void animateParallel() {
ViewAnimator.animate(mountain, image)
.dp().translationY(-1000, 0)
.alpha(0, 1)
.andAnimate(percent)
.scale(0, 1)
.andAnimate(text)
.dp().translationY(1000, 0)
.textColor(Color.BLACK, Color.WHITE)
.backgroundColor(Color.WHITE, Color.BLACK)
.waitForHeight()
.interpolator(new AccelerateDecelerateInterpolator())
.duration(1000)
.thenAnimate(percent)
.custom(new AnimationListener.Update<TextView>() {
@Override
public void update(TextView view, float value) {
value = value * 100;
view.setText(String.format(Locale.US, "%.0f%%", value));
}
}, 0, 1)
.andAnimate(image)
.rotation(0, 360)
.onStop(new AnimationListener.Stop() {
@Override
public void onStop() {
Intent intent = new Intent(StartActivity.this, MainActivity.class);
startActivity(intent);
}
})
.duration(1000)
.start();
}
recycleView动画效果

效果如下:
示例代码
recyclerView= (RecyclerView) findViewById(R.id.id_recyclerview);
recyclerView.setLayoutManager(new GridLayoutManager(this, 4));
mAdapter=new HomeAdapter();
slideInBottomAnimatorAdapter=new SlideInBottomAnimatorAdapter(mAdapter,recyclerView);
recyclerView.setAdapter(slideInBottomAnimatorAdapter);
