android 剪贴板 ClipboardManager

  想做文件管理器中对文件的复制和粘贴功能。想到用ClipboardManager，其中可以放三种数据 text、intent、uri，为ClipData类型。我用的uri做了个小demo，话不多说上代码。

布局文件activity_main.xml

2.java文件

package com.example.clipboard;

import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Activity;
import android.content.ClipData;
import android.content.ClipboardManager;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity implements OnClickListener {
	private ClipboardManager clipboard = null;
	private final String PATH = "/mnt/sdcard/GPS.LOG";
	private TextView textView;
	private Button copyButton;
	private Button pasteButton;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		textView = (TextView) this.findViewById(R.id.text);
		copyButton = (Button) this.findViewById(R.id.copy_button);
		pasteButton = (Button) this.findViewById(R.id.paste_button);
		copyButton.setOnClickListener(this);
		pasteButton.setOnClickListener(this);

	}

	@TargetApi(Build.VERSION_CODES.HONEYCOMB)
	@SuppressLint("NewApi")
	private void setclip() {
		//获得ClipboardManager对象
		clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
		//需要存入的内容
		Uri uri = Uri.parse(PATH);
		//项内容转换为ClipData对象
		ClipData clipData = ClipData.newUri(getContentResolver(), "URI", uri);
		//存入剪贴板
		clipboard.setPrimaryClip(clipData);

	}

	@TargetApi(Build.VERSION_CODES.HONEYCOMB)
	@SuppressLint("NewApi")
	private String getclip() {
		clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
	ClipData.Item data=	clipboard.getPrimaryClip().getItemAt(0);
	Uri uri=data.getUri();
	//	String str = clipboard.getPrimaryClip().toString();
		String path = uri.getEncodedPath();
		return path;
	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch (v.getId()) {
		case R.id.copy_button:
			setclip();
			break;
		case R.id.paste_button:
			textView.setText("剪贴板内容："+getclip());
			break;
		default:
			break;
		}

	}

}

运行结果：
