android 剪贴板 ClipboardManager

来源：互联网发布：linux shell exit 1 编辑：程序博客网时间：2024/05/01 05:08

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

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity" >    <TextView        android:id="@+id/text"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="剪切板" />    <Button        android:id="@+id/copy_button"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_below="@id/text"        android:text="点击复制" />    <Button        android:id="@+id/paste_button"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_below="@id/copy_button"        android:text="点击粘贴" /></RelativeLayout>

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;@Overrideprotected 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;}@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch (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：
