Android 中发送和接收短信

38: android:layout_width="fill_parent"

39: android:layout_height="wrap_content"

40: android:gravity="center"

41: android:id="@+id/btnSend"

42: android:paddingTop="20sp"

43: / >

44: < /LinearLayout >

3.创建一个Java类文件，导入以下包：

1: import java.util.regex.Matcher;

2: import java.util.regex.Pattern;

3: import com.eshore.smsManagers.R;

4: import android.app.Activity;

5: import android.telephony.gsm.*;

6: import android.view.View;

7: import android.view.View.OnClickListener;

8: import android.widget.Button;

9: import android.widget.EditText;

10: import android.widget.Toast;

11: import android.os.Bundle;

4.重写onCreate方：

1: txtFrom=(EditText)this.findViewById(R.id.txt_from);

2: txtContent=(EditText)this.findViewById(R.id.txt_content);

3: btnSend=(Button)this.findViewById(R.id.btnSend);

4: btnSend.setOnClickListener(new OnClickListener() {

5: public void onClick(View v) {

6: if(!validate())

7: return;

8: SmsManager.getDefault().sendTextMessage(txtFrom.getText().toString().trim(),null,txtContent.getText().toString(),null,null);

9: txtFrom.setText("");

10: txtContent.setText("");

11: Toast toast=Toast.makeText(main.this, "短信发送成功!",Toast.LENGTH_LONG);

12: toast.show();

13: }

14: });

相关的辅助方法有手机的合法性验证和短信内容不可为空：

1: //合法性验证

2: private boolean validate(){

3: String mobile=txtFrom.getText().toString().trim();

4: String content=txtContent.getText().toString();

5: if(mobile.equals("")){

6: Toast toast=Toast.makeText(this, "手机号码不能为空!",Toast.LENGTH_LONG);
