Android之路——第二个Android小程序（Android短信发送）

闲话不说，继续贴代码：

首先是布局的代码：main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView 
	android:text="@string/inputMobile" 
	android:layout_width="fill_parent" 
	android:layout_height="wrap_content">
</TextView>
<EditText 
	android:id="@+id/mobile" 
	android:layout_width="fill_parent" 
	android:layout_height="wrap_content">
</EditText>
<TextView 
	android:text="@string/inputMessage"
	android:layout_width="fill_parent" 
	android:layout_height="wrap_content">
</TextView>
<EditText 
	android:id="@+id/Message" 
	android:layout_width="fill_parent" 
	android:layout_height="wrap_content">
</EditText>
<Button 
	android:text="@string/Submit" 
	android:id="@+id/Submit" 
	android:layout_width="wrap_content" 
	android:layout_height="wrap_content">
</Button>
</LinearLayout>

接下来是String.xml的代码：

<?xml version="1.0" encoding="utf-8"?>
<resources>
	<string name="app_name">短信发送器</string>
	<string name="inputMobile">请输入手机号：</string>
	<string name="inputMessage">请输入短信内容：</string>
	<string name="Submit">发送短信</string>
</resources>

上面两个都是位于res里面的。

接下来是src里面的代码MessageActivity：(由于在公司，没空写注释，等等回去补上)

package cn.jason.android;
import java.util.List;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.gsm.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class messageActivity extends Activity {
	/** Called when the activity is first created. */
	@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        final EditText mobileNoEditText = (EditText) findViewById(R.id.mobile);
        final EditText messageEditText = (EditText) findViewById(R.id.Message);
        Button submitButton =  (Button) findViewById(R.id.Submit);
        
        submitButton.setOnClickListener(new View.OnClickListener() {
			
			public void onClick(View view) {
				String moblileString = mobileNoEditText.getText().toString();
		        String messageString = messageEditText.getText().toString();
		        SmsManager smsManager = SmsManager.getDefault();
		        PendingIntent sendingIntent = PendingIntent.getBroadcast(messageActivity.this, 0, new Intent(), 0);
		        List<String> msgsList = smsManager.divideMessage(messageString);
		        for (String msg : msgsList) {
					smsManager.sendTextMessage(moblileString, null, msg, sendingIntent, null);
				}
		        Toast.makeText(messageActivity.this, "短信发送成功", Toast.LENGTH_LONG).show();
			}
		});
        
        
        
    }
}

以上你都写了还是不能用的，最关键的一句是这样的：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="cn.jason.android"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".messageActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="4" />
	<uses-permission android:name="android.permission.SEND_SMS" />
</manifest>

上面的最后一句如果没有的话是没法发短信的。这个是权限的设置。短信发送权限的设置。<uses-permission android:name="android.permission.SEND_SMS" />
