android输入法ImeOptions

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

 

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

 

 

 

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

 

在这里设置的imeOptions如何使用呢？如下面的代码，让EditText实现setOnEditorActionListener，在onEditAction方法中actionId就对应我们设置的imeOptions。系统默认的actionId有：EditorInfo.IME_NULL、EditorInfo.IME_ACTION_SEND、EditorInfo.IME_ACTION_DONE等。这样我们就可以根据不同的EditText来实现不同的软键盘右下角功能键。

 package com.test;

 import com.test.main.TestAsyn;

 import android.app.Activity;
 import android.os.Bundle;
 import android.view.KeyEvent;
 import android.view.inputmethod.EditorInfo;
 import android.widget.EditText;
 import android.widget.TextView;
 import android.widget.TextView.OnEditorActionListener;
 import android.widget.Toast;

 public class IMFActivity extends Activity implements OnEditorActionListener {

     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(this);
         etEmail.setOnEditorActionListener(this);
         etNumber.setOnEditorActionListener(this);

     }

     @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;
         }
         //Toast.makeText(this, v.getText()+"--" + actionId, Toast.LENGTH_LONG).show();
         return true;
     }
 }
