使用ClipboardManager剪贴板实现复制粘贴功能

来源：互联网发布：螺纹期货软件编辑：程序博客网时间：2024/04/29 00:58

经常要使用复制粘贴的功能，比如长安一个TextView弹出一个Pop，Pop中有一个选项“复制文本”，点击这个选项就把内容复制到了剪贴板上。

注意SDK11之前请使用android.text.ClipboardManager ，
SDK11起android.text.ClipboardManager被废弃，使用它的子类android.content.ClipboardManager替代，同样被废弃还有setText/getText/hasText方法，使用setPrimaryClip/getPrimaryClip/hasPrimaryClip替代

import android.annotation.SuppressLint;import android.app.Activity;import android.content.ClipData;import android.content.ClipboardManager;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {   private ClipboardManager myClipboard;   private ClipData myClip;   private EditText copyField,pasteField;   @Override   protected void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.activity_main);      myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);      copyField = (EditText)findViewById(R.id.editText1);      pasteField = (EditText)findViewById(R.id.editText2);   }   @SuppressLint("NewApi")   public void copy(View view){      String text = copyField.getText().toString();      myClip = ClipData.newPlainText("text", text);      myClipboard.setPrimaryClip(myClip);      Toast.makeText(getApplicationContext(), "Text Copied",       Toast.LENGTH_SHORT).show();   }   @SuppressLint("NewApi")   public void paste(View view){      ClipData abc = myClipboard.getPrimaryClip();      ClipData.Item item = abc.getItemAt(0);      String text = item.getText().toString();      pasteField.setText(text);      Toast.makeText(getApplicationContext(), "Text Pasted",       Toast.LENGTH_SHORT).show();   }   @Override   public boolean onCreateOptionsMenu(Menu menu) {      // Inflate the menu; this adds items to the action bar if it is present.      getMenuInflater().inflate(R.menu.main, menu);      return true;   }}

布局：

<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/textView1"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignParentLeft="true"      android:layout_alignParentTop="true"      android:layout_marginLeft="25dp"      android:layout_marginTop="19dp"      android:text="@string/copytext"      android:textAppearance="?android:attr/textAppearanceLarge" />   <EditText      android:id="@+id/editText1"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignLeft="@+id/textView1"      android:layout_below="@+id/textView1"      android:layout_marginTop="20dp"      android:ems="10" >      <requestFocus />   </EditText>   <TextView      android:id="@+id/textView2"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignLeft="@+id/editText1"      android:layout_centerVertical="true"      android:text="@string/pastetext"      android:textAppearance="?android:attr/textAppearanceLarge" />   <Button      android:id="@+id/button1"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignLeft="@+id/editText1"      android:layout_below="@+id/editText1"      android:layout_marginLeft="65dp"      android:layout_marginTop="20dp"      android:onClick="copy"      android:text="@string/copy" />   <EditText      android:id="@+id/editText2"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignLeft="@+id/textView2"      android:layout_below="@+id/textView2"      android:layout_marginTop="39dp"      android:ems="10" />   <Button      android:id="@+id/button2"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignLeft="@+id/button1"      android:layout_below="@+id/editText2"      android:layout_marginTop="34dp"      android:onClick="paste"      android:text="@string/paste" /></RelativeLayout>
