android_Android应用开发之（android:imeOptions）

在做应用开发时，用户在用EditText进行输入时，我们可以充分利用软键盘特色功能进行导航，给用户提供好的用户体验。

举例说明android:imeOptions 属性特点

1    默认情况下软键盘右下角的按钮为“下一个”，点击会到下一个输入框，保持软键盘

2    android:imeOptions="actionSend"软键盘下方变成“发送”，点击后光标移动下一个

3    设置android:imeOptions="actionDone"，软键盘下方变成“完成”，点击后光标保持在原来的输入框上，并且软键盘关闭

使用方法 给EditText 设置OnEditorActionListener，然后进行相应处理

附上Demo代码

public class IMFActivity extends Activity {  

 

EditText etDefault;  

EditText etEmail;  

EditText etNumber;  

 

/** Called when the activity is first created. */  

@Override  

public void onCreate(Bundle savedInstanceState) {  

   super.onCreate(savedInstanceState);  

   setContentView(R.layout.imf_layout);  

     

   etDefault = (EditText)findViewById(R.id.default_content);  

   etEmail = (EditText)findViewById(R.id.email_content);  

   etNumber = (EditText)findViewById(R.id.number_content);  

   etDefault.setOnEditorActionListener(onEditorActionListener);  

   etEmail.setOnEditorActionListener(onEditorActionListener);  

   etNumber.setOnEditorActionListener(onEditorActionListener);  

     

}  

 

private OnEditorActionListener onEditorActionListener = new OnEditorActionListener() {

   

   @Override

   public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

       switch(actionId){  

       case EditorInfo.IME_NULL:  

           System.out.println("null for default_content: " + v.getText() );  

           break;  

       case EditorInfo.IME_ACTION_SEND:  

           System.out.println("action send for email_content: "  + v.getText());  

           break;  

       case EditorInfo.IME_ACTION_DONE:  

           System.out.println("action done for number_content: "  + v.getText());  

           break;  

       }  

       return true;

   }

};

}
