Android进程间通讯——Clipboard(剪切板)

剪贴板的含义也很好理解，就是一个进程在剪贴板里面复制了一条数据，然后另外一个进程再调用粘贴方法，把数据取出来。

进程A的代码：

public class ClipboardOneActivity extends Activity {
	private Button mBtnWriteClipBoard;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.clipboard);
		mBtnWriteClipBoard = (Button) findViewById(R.id.button1); //实例化我们的按钮
		mBtnWriteClipBoard.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				ClipboardManager cm=(ClipboardManager) ClipboardOneActivity.this.getSystemService(CLIPBOARD_SERVICE);
				cm.setText( "Hello World!");
			}
		});
	}
}

进程B的代码（在好另新建一个工程）

public class ClipboardTwoActivity extends Activity {
	private Button mBtnReadClip;
	private TextView textView;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		mBtnReadClip  = (Button) findViewById(R.id.button1);
		textView=(TextView) findViewById(R.id.textView1);
		mBtnReadClip.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				ClipboardManager cm=(ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
				textView.setText(cm.getText());
			}
		});
	}
}

没什么好说的，将上面的代码copy到工程中实验一下就知道了
