Android属性-android:imeOptions

本文转自：http://liliang1222.iteye.com/blog/1130062

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。

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;
    }
}
