具体代码如下所示:

import com.org.wangfeng.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class GetPhoneActivity extends Activity {
private EditText editText;
private Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.getphoneactivity);
editText = (EditText) findViewById(R.id.et_getphone);
button = (Button) findViewById(R.id.bb_getphone);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(GetPhoneActivity.this,
ContactActivity.class);
startActivityForResult(intent, 1);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// System.out.println("resultCode:" + resultCode);
// System.out.println("requestCode:" + requestCode);
Log.d("jiejie", "被调用了");
if (resultCode == Activity.RESULT_OK) {
String phone = data.getStringExtra("phone");
Log.d("jiejie", "_______________"+phone);
phone = phone.replaceAll("-", "").replaceAll(" ", "");// 替换-和空格
editText.setText(phone);// 把电话号码设置给输入框
}
super.onActivityResult(requestCode, resultCode, data);
}
}
