3.效果按下时它被achived所述的EditText下一个空间PoPing键盘的由 创建一个空的RelativeLayout作为容器到键盘发挥功能：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<com.galrom.keyboard.EditTextNoKeyBoard
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/Key_board_container"
android:layout_centerHorizontal="true"
android:clickable="true"
android:ems="10" />
<RelativeLayout
android:id="@+id/Key_board_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="38dp"
android:background="#ffffff" >
</RelativeLayout>
当用户按下EditText时，我们将片段添加到容器中，当他按下时，我们将其隐藏。键盘片段通过onKeyBoardEvent interace与Activity交流。 注意：托管活动必须实现此接口，否则将抛出ClassCastException。
非常重要：我没有处理方向更改，如果在键盘打开时更改为ladscape，它将崩溃，因此禁用横向模式或处理方向更改以避免key_board_fragment上的nullPointerException。
这是implemets键盘的活动：
package com.galrom.keyboard;
import com.example.calculator.R;
import android.content.res.Configuration;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends FragmentActivity implements KeyBoardFragment.onKeyBoardEvent{
private EditText et;
private KeyBoardFragment keyboard_fragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et=(EditText)findViewById(R.id.editText1);
et.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(keyboard_fragment==null)
{
keyboard_fragment=KeyBoardFragment.newInstance(et.getText().toString());
getSupportFragmentManager().beginTransaction().add(R.id.Key_board_container, keyboard_fragment).commit();
}
else
{
if(keyboard_fragment.isVisible())
getSupportFragmentManager().beginTransaction().hide(keyboard_fragment).commit();
else
{
keyboard_fragment=KeyBoardFragment.newInstance(et.getText().toString());
getSupportFragmentManager().beginTransaction().add(R.id.Key_board_container, keyboard_fragment).commit();
}
}
});
}
@Override
public void numberIsPressed(String total) {
// TODO Auto-generated method stub
et.setText(total);
}
@Override
public void doneButtonPressed(String total) {
// TODO Auto-generated method stub
et.setText(total);
if(keyboard_fragment.isVisible())
getSupportFragmentManager().beginTransaction().hide(keyboard_fragment).commit();
}
@Override
public void backLongPressed() {
// TODO Auto-generated method stub
et.setText("");
}
@Override
public void backButtonPressed(String total) {
// TODO Auto-generated method stub
et.setText(total);
}
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
if(keyboard_fragment!=null)
{
if(keyboard_fragment.isVisible())
getSupportFragmentManager().beginTransaction().remove(keyboard_fragment).commit();
else
super.onBackPressed();
}
else
super.onBackPressed();
}
}
和最后一件事： 禁用的Android非标准键盘我已经创建了一个简单的返回，在虚假的CustomEditText的空间PoPing：onCheckIsTextEditor（ ），这是CustomEditText类：
package com.galrom.keyboard;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.EditText;
public class EditTextNoKeyBoard extends EditText {
public EditTextNoKeyBoard(Context context) {
super(context);
}
public EditTextNoKeyBoard(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public EditTextNoKeyBoard(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean onCheckIsTextEditor() {
// TODO Auto-generated method stub
return false;
}
}
希望它可以帮助你了... 如果你有改进的建议，我将很高兴听到。 Gal。
setRawInputType（Configuration.KEYBOARD_12KEY）给你什么？ – yarian 2013-02-26 21:51:10
