Question

尝试使用以下代码来运行应用程序，但是收到以下错误。“Manifest merger失败，出现多个错误，请参阅日志”。我之前在应用程序gradle文件中做了一些更改，因为应用程序涉及使用“CardView和Recycler视图”（在stackoverflow中的几个问题上建议进行更改）附加下面的所有应用程序文件。有人可以帮我这个吗？ Gradle控制台：

    package com.example.sumeet.cardviewreclyerview_try1;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;

public class MainActivity extends AppCompatActivity {

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_home, menu);
        return super.onCreateOptionsMenu(menu);
    }
}

MainActivity.java

package com.example.sumeet.cardviewreclyerview_try1;

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

/**

public class VersionAdapter extends RecyclerView.Adapter<VersionAdapter.VersionViewHolder> {

    private String[] version = {"Alpha", "Beta", "CupCake", "Donut", "Eclair", "Froyo", "Gingerbread", "Honeycomb", "Ice Cream Sandwich", "Jelly Bean", "KitKat", "Lollipop", "Marshmallow", "Nougat", "O"};

    @Override
    public VersionAdapter.VersionViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {


        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.each_row, parent, false);
        VersionViewHolder viewHolder = new VersionViewHolder(v);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(VersionAdapter.VersionViewHolder holder, int position) {
        holder.text.setText(version[position]);
    }

    @Override
    public int getItemCount() {
        return version.length;
    }

    public static class VersionViewHolder extends RecyclerView.ViewHolder {
        private TextView text;

        public VersionViewHolder(View itemView) {
            super(itemView);
            text = (TextView) itemView.findViewById(R.id.textview_card);
        }
    }
}

您正在尝试使用Android支持库的多个版本：

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:22.2.0'
compile 'com.android.support:recyclerview-v7:+'

对所有 com.android.support工件使用相同版本。那个版本不应该是+。鉴于这三行，我会选择25.3.1。

尝试使用以下代码来运行应用程序但是收到以下错误。“Manifest merger失败，出现多个错误，请参阅日志”
