AndroidSweetSheet：ViewPager的实现（2）


AndroidSweetSheet：ViewPager的实现（2）

附录文章9说明了AndroidSweetSheet典型的列表样式实现，本文写一个例子，说明AndroidSweetSheet以翻页的ViewPager样式实现。本例所需的布局文件和附录文章9相同，只是上层Java代码不同而已：

package zhangphil.demo;

import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.RelativeLayout;
import android.widget.Toast;

import com.mingle.entity.MenuEntity;
import com.mingle.sweetpick.DimEffect;
import com.mingle.sweetpick.SweetSheet;
import com.mingle.sweetpick.ViewPagerDelegate;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

private SweetSheet mSweetSheet;
private RelativeLayout rl;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

rl = (RelativeLayout) findViewById(R.id.root);

findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mSweetSheet.isShow())
mSweetSheet.dismiss();
else
mSweetSheet.show();
}
});

setupViewpager();
}

private void setupViewpager() {
mSweetSheet = new SweetSheet(rl);

final ArrayList<MenuEntity> list = new ArrayList<>();
for (int i = 0; i < 100; i++) {
MenuEntity menuEntity = new MenuEntity();
menuEntity.iconId = R.mipmap.ic_launcher;
menuEntity.titleColor = Color.RED;
menuEntity.title = "zhang phil @ csdn " + i;
list.add(menuEntity);
}

// SweetSheet 控件,根据 rl 确认位置
mSweetSheet = new SweetSheet(rl);

//设置数据源 (数据源支持设置 list 数组,也支持从菜单中获取)
//如果是从菜单中加载，那么是 .setMenuList(R.menu.menu_sweet);
mSweetSheet.setMenuList(list);

//从menu 中设置数据源
//mSweetSheet.setMenuList(R.menu.menu_sweet);

//ViewPager样式的底部面板
mSweetSheet.setDelegate(new ViewPagerDelegate());

mSweetSheet.setBackgroundEffect(new DimEffect(10f));
mSweetSheet.setOnMenuItemClickListener(new SweetSheet.OnMenuItemClickListener() {
@Override
public boolean onItemClick(int position, MenuEntity menuEntity) {

Toast.makeText(MainActivity.this, menuEntity.title + "  " + position, Toast.LENGTH_SHORT).show();

return true;
}
});
}

/**
private void setupRecyclerView() {
final ArrayList<MenuEntity> list = new ArrayList<>();
for (int i = 0; i < 10; i++) {
MenuEntity menuEntity = new MenuEntity();
menuEntity.iconId = R.mipmap.ic_launcher;
menuEntity.titleColor = Color.RED;
menuEntity.title = "zhang phil @ csdn " + i;
list.add(menuEntity);
}

// SweetSheet 控件,根据 rl 确认位置
mSweetSheet = new SweetSheet(rl);

//设置数据源 (数据源支持设置 list 数组,也支持从菜单中获取)
//如果是从菜单中加载，那么是 .setMenuList(R.menu.menu_sweet);
mSweetSheet.setMenuList(list);

//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 来显示背景效果
// BlurEffect:模糊效果.
// DimEffect 变暗效果
mSweetSheet.setBackgroundEffect(new DimEffect(10f));

//设置点击事件
mSweetSheet.setOnMenuItemClickListener(new SweetSheet.OnMenuItemClickListener() {
@Override
public boolean onItemClick(int position, MenuEntity menuEntity) {
//即时改变当前项的颜色
list.get(position).titleColor = Color.GREEN;

((RecyclerViewDelegate) mSweetSheet.getDelegate()).notifyDataSetChanged();

Toast.makeText(MainActivity.this, menuEntity.title + "  " + position, Toast.LENGTH_SHORT).show();

//根据返回值, true 会关闭 SweetSheet ,false 则不会.
return false;
}
});
}
**/

@Override
public void onBackPressed() {
if (mSweetSheet.isShow()) {
mSweetSheet.dismiss();
} else {
super.onBackPressed();
}
}
}
