Android单击复制TextView文本

总共2步实现：

1.创建CopyButtonLibrary.java

package com.huatec.danyizz.utils;
import android.content.ClipData;
import android.content.ClipboardManager;
import android.content.Context;
import android.widget.TextView;
import android.widget.Toast;

import static android.content.Context.CLIPBOARD_SERVICE;

/**

public class CopyButtonLibrary {

    private ClipboardManager myClipboard;
    private ClipData myClip;
    private Context context;
    private TextView textView;

    public CopyButtonLibrary(Context context, TextView textView) {
        this.context = context;
        this.textView = textView;
    }

    public void init() {
        myClipboard = (ClipboardManager) context.getSystemService(CLIPBOARD_SERVICE);
        String text;
        text = textView.getText().toString();

        myClip = ClipData.newPlainText("text", text);
        myClipboard.setPrimaryClip(myClip);

        Toast.makeText(context, text + " 已复制", Toast.LENGTH_SHORT).show();
    }

}

2.使用：

        //监听点击事件
        final TextView textView = findViewById(R.id.textview);//文字
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //传入需要复制的文字的控件
                CopyButtonLibrary copyButtonLibrary = new CopyButtonLibrary(getApplicationContext(),textView);
                copyButtonLibrary.init();
            }
        });
