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。

Java代码



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;

}

}
