RecyclerView 点击事件 ,条目的排列样式_综合

RecyclerView 条目的点击事件 要自定义,在RecyclerViewAdapter 中定义接口提供回调,这里自定义了条目的点击事件和长按事件 如下

holder.mTextView.setText(mData.get(position));
holder.mTextView.setOnClickListener(new View.OnClickListener() {@Override
    public void onClick(View v) {if (mItemClickListener!=null){mItemClickListener.onItemClick(position);}}
});
holder.mTextView.setOnLongClickListener(new View.OnLongClickListener() {@Override
    public boolean onLongClick(View v) {if (mItemClickListener!=null){mItemClickListener.onItemLongClick(position);}return false;}
});

在 Activity 中回调

recyclerViewAdapter.setItemClickListener(new RecyclerViewAdapter.OnItemClickListener() {@Override
    public void onItemClick(int position) {Toast.makeText(MainActivity.this, "点击OK--->" + position, Toast.LENGTH_SHORT).show();if (position == 1) {notification();}}@Override
    public void onItemLongClick(int position) {Toast.makeText(MainActivity.this, "长按--点击OK--->" + position, Toast.LENGTH_SHORT).show();}
});

设置条目的排列样式

  //设置条目的排列样式
        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
//        StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(4, StaggeredGridLayoutManager.VERTICAL);
        mRecyclerView.setLayoutManager(linearLayoutManager);

import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
