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.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;
}
}
