工作日志记录,最近工作上有一个设计效果类似于BottomSheetDialog的效果,这里做了一个demo,记录下实现的效果和代码,方便以后可以参照一下:
注意:使用这个BottomSheetDialog时候要映入对应得MaterialDesign包,我这里是androidx版本所有使用
compile 'com.google.android.material:material:1.0.0',如果是appconpact包编译,可以使用as上的refactor->Migrate to Appcompact来转成appcompact兼容。
实现效果如下:
MainActivity.java代码如下(具体实现):
package com.xuganwen.testdrag;
import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.GridLayoutManager;
import androidx.recyclerview.widget.ItemTouchHelper;
import androidx.recyclerview.widget.RecyclerView;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import com.chad.library.adapter.base.callback.ItemDragAndSwipeCallback;
import com.chad.library.adapter.base.listener.OnItemDragListener;
import com.google.android.material.bottomsheet.BottomSheetBehavior;
import com.google.android.material.bottomsheet.BottomSheetDialog;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private RecyclerView recycleview;
// private MyAdapter myAdapter;
private MyAdapter myAdapter;
private SimpleCycleProgressView progressview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recycleview = findViewById(R.id.recycleview);
final List<String> list = new ArrayList<>();
for (int i = 0; i < 60; i++) {
list.add(i + "hehe");
}
//第一种方式使用 com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30库提供的adapter的扩展方法来实现,实际上也是在第二种方式的基础上再做简易封装
myAdapter = new MyAdapter(R.layout.item,list);
recycleview.setLayoutManager(new GridLayoutManager(this, 4));
recycleview.setAdapter(myAdapter);
ItemDragAndSwipeCallback itemDragAndSwipeCallback = new ItemDragAndSwipeCallback(myAdapter);
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(itemDragAndSwipeCallback);
itemTouchHelper.attachToRecyclerView(recycleview);
myAdapter.enableDragItem(itemTouchHelper, R.id.tv, true);
OnItemDragListener onItemDragListener = new OnItemDragListener() {
@Override
public void onItemDragStart(RecyclerView.ViewHolder viewHolder, int pos){}
@Override
public void onItemDragMoving(RecyclerView.ViewHolder source, int from, RecyclerView.ViewHolder target, int to) {}
@Override
public void onItemDragEnd(RecyclerView.ViewHolder viewHolder, int pos) {
Log.i("xuganwenlog", list.toString());
}
};
myAdapter.setOnItemDragListener(onItemDragListener);
final BottomSheetDialog dialog = new BottomSheetDialog(this);
View view = View.inflate(this, R.layout.bottom_sheet_layout, null);
dialog.setContentView(view);
RecyclerView recycleview = view.findViewById(R.id.recycleview);
recycleview.setLayoutManager(new GridLayoutManager(this, 4));
recycleview.setAdapter(myAdapter);
final BottomSheetBehavior<View> mDialogBehavior = BottomSheetBehavior.from((View) view.getParent());
mDialogBehavior.setPeekHeight(getResources().getDisplayMetrics().heightPixels/3);
mDialogBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dialog.dismiss();
mDialogBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
});
dialog.show();
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
dialog.show();
}
});
}
}
简单实例,这里不再赘述。
