Android实现短信息发送

      对于短信发送器的实现，也是较简单的，总体来说只需要设置好布局文件和Activity类就可以了，但在此基础上，还需要进行对配置文件的设置，下面就让我们来进行演示：

在创建好项目之后，配置布局文件代码如下所示：

 其中使用了组件AutoCompleteTextView组件，能够有提示的出现语句，在这儿我们用于提示电话号码，比如输入188时，再输入1时就会有提示188这个电话号码，在内容输入区，我们使用一个文本编辑框进行信息内容的传送，最后来一个发送按钮就可以完成布局了

<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="com.wusu.android_002_Message.MainActivity" >

    <AutoCompleteTextView
        android:id="@+id/editText_receive"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="5dp"
        android:inputType="number"
        android:hint="@string/Input_number_of_receive"
        android:ems="10" />

        <EditText
            android:id="@+id/editText_content"
            android:layout_width="fill_parent"
            android:layout_height="match_parent"
            android:layout_above="@+id/button_send"
            android:layout_alignRight="@+id/editText_receive"
            android:layout_below="@id/editText_receive"
            android:ems="10"
            android:layout_marginTop="10dp"
            android:hint="@string/Input_content"
            android:gravity="top"
            android:inputType="textMultiLine" >

        <requestFocus />
    </EditText>

    <Button
        android:id="@+id/button_send"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignRight="@+id/editText_content"
        android:layout_marginBottom="36dp"
        android:layout_marginRight="14dp"
        android:text="@string/send" />

</RelativeLayout>

在写完布局之后，我们进行Activity类的编写，主要代码如下所示：

public class MainActivity extends Activity implements OnClickListener {
	private Button button_send;
	private TextView textView_content,textView_receive;
  private AutoCompleteTextView autoCompleteTextView_number;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		button_send=(Button) findViewById(R.id.button_send);
	    button_send.setOnClickListener(this);
		textView_content=(TextView) findViewById(R.id.editText_content);
		textView_receive=(TextView) findViewById(R.id.editText_receive);
		   autoCompleteTextView_number=(AutoCompleteTextView) findViewById(R.id.editText_receive);
	       ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,numbers);
	       autoCompleteTextView_number.setAdapter(adapter);
	}
//显示要提示的电话号码
	 private String[] numbers={"1880","150","1008611","10086","151","1234567890","9876543210","725610987678","226610"}; 

	@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;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		int id = item.getItemId();
		if (id == R.id.action_settings) {
			finish();
			
			return true;
		}
		return super.onOptionsItemSelected(item);
	}

	@Override
	public void onClick(View view) 
	{
		switch (view.getId()) {
		case R.id.button_send:
			String content=textView_content.getText().toString();
			String number=textView_receive.getText().toString();
			if(TextUtils.isEmpty(number))
			{
				Toast.makeText(MainActivity.this,"请输入电话号码...", Toast.LENGTH_SHORT).show();
			  return;
			}
			else
			{
				SmsManager smsManager=SmsManager.getDefault();
				ArrayList<String> contents=smsManager.divideMessage(content);
				for(String str:contents)
				{
				smsManager.sendTextMessage(number,null, str, null, null);
			    }
				Toast.makeText(this, "已发送", Toast.LENGTH_SHORT).show();
			}
			break;

		default:
			break;
		}
	}
}

现在，在进行配置文件，只需在配置文件中添加即可

 <uses-permission android:name="android.permission.SEND_SMS"/>

以上就是Android中短信息发送功能的实现
