Recyclerview style

以下是 recyclerview 的其中的一种样式如下效果：

1.首先在 app.gralde下

 compile 'com.android.support:recyclerview-v7:23.2.1' compile 'com.android.support:cardview-v7:23.0.1'

导入。

2.activity.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/activity_main"    android:layout_width="match_parent"    android:layout_height="match_parent">    <android.support.v7.widget.RecyclerView            android:id="@+id/recycler_view"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:scrollbars="vertical"></android.support.v7.widget.RecyclerView>    </RelativeLayout>

3.建一个custom.xml

<?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:card_view="http://schemas.android.com/apk/res-auto"    android:id="@+id/card_view"    card_view:cardCornerRadius="4dp"    card_view:cardElevation="1dp"    card_view:cardMaxElevation="2dp"    android:layout_width="match_parent"    android:layout_height="wrap_content">    <TextView        android:id="@+id/tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_margin="2dp"        android:fontFamily="sans-serif-condensed"        android:gravity="center"        android:padding="5dp"        android:textColor="#000"        android:textSize="20dp"/></android.support.v7.widget.CardView>

Mactivity.java代码

package listview.mifeng.us.recyclerviewdemo;import android.content.Context;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.support.v7.widget.RecyclerView;import android.graphics.Color;import android.graphics.drawable.ColorDrawable;import android.support.v7.widget.StaggeredGridLayoutManager;import android.view.Window;import android.widget.RelativeLayout;public class MainActivity extends AppCompatActivity {    private Context mContext;    private RecyclerView mRecyclerView;    private RecyclerView.Adapter mAdapter;    private RecyclerView.LayoutManager mLayoutManager;    @Override    protected void onCreate(Bundle savedInstanceState) {        requestWindowFeature(Window.FEATURE_ACTION_BAR);         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);        mContext = getApplicationContext();        getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.RED));        mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);        String[] colors = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N"};        mLayoutManager = new StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.VERTICAL);        mRecyclerView.setLayoutManager(mLayoutManager);        mAdapter = new ColorAdapter(mContext, colors);        mRecyclerView.setAdapter(mAdapter);    }}

ColorAdpter 代码

package listview.mifeng.us.recyclerviewdemo;/** * Created by 孙贝贝 on 2016/11/23. */import android.support.v7.widget.RecyclerView;import android.content.Context;import android.graphics.Color;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;import java.util.Random;public class ColorAdapter extends RecyclerView.Adapter<ColorAdapter.ViewHolder> {    private String[] mDataSet;    private Context mContext;    private Random mRandom = new Random();    public ColorAdapter(Context context, String[] DataSet) {        mDataSet = DataSet;        mContext = context;    }    public static class ViewHolder extends RecyclerView.ViewHolder {        public TextView mTextView;        public ViewHolder(View v) {            super(v);            mTextView = (TextView) v.findViewById(R.id.tv);        }    }    @Override    public ColorAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View v = LayoutInflater.from(mContext).inflate(R.layout.custom_view, parent, false);        ViewHolder vh = new ViewHolder(v);        return vh;    }    @Override    public void onBindViewHolder(ViewHolder holder, int position) {        holder.mTextView.setText(mDataSet[position]);        holder.mTextView.getLayoutParams().height = getRandomIntInRange(250, 75);        holder.mTextView.setBackgroundColor(getRandomHSVColor());    }    @Override    public int getItemCount() {        return mDataSet.length;    }    protected int getRandomIntInRange(int max, int min) {        return mRandom.nextInt((max - min) + min) + min;    }    protected int getRandomHSVColor() {        int hue = mRandom.nextInt(361);        float saturation = 1.0f;        float value = 1.0f;        int alpha = 255;        int color = Color.HSVToColor(alpha, new float[]{hue, saturation, value});        return color;    }}

如以上就可以完成效果；
