我遇到了同样的问题,我发现没有像这样可用的安卓键盘,唯一的方法是实现你自己的。所以我想和你分享我的工具,希望能为你节省一些宝贵的时间:
我已经创建了这个 xml,您可以根据需要修改键盘的颜色、字体和大小:

我创建了这个片段:

import android.widget.Button;
public class KeyBoardFragment extends Fragment {

return fragment;
}
@Override
public void onAttach(Activity activity) {

}
catch(ClassCastException e)
{

currentLength=sb.length();
View rootView=inflater.inflate(R.layout.numeric_keyboard_layout, container, false);
one_btn=(Button)rootView.findViewById(R.id.one_btn);
one_btn.setOnClickListener(new View.OnClickListener() {
@Override

// TODO Auto-generated method stub
add("1");
}
});
two_btn=(Button)rootView.findViewById(R.id.two_btn);
two_btn.setOnClickListener(new View.OnClickListener() {

3.EditText下弹出键盘的效果是通过创建一个空的RelativeLayout来实现的,该RelativeLayout用作键盘的容器:
<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,当他按下完成时,我们将其隐藏。键盘片段通过 onKeyBoardEvent 交互与 Activity 通信。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,如果您在键盘打开时更改为 ladscape,它将崩溃,因此请禁用横向模式或处理方向更改以避免 key_board_fragment 上的 nullPointerException。
这是实现键盘的活动:
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();
}
}
最后一件事:为了禁用 android 标准键盘的弹出,我创建了一个 CustomEditText,它只在以下位置返回 false: 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;
}
}
希望它对您有所帮助...如果您有改进的建议,我将很高兴听到。加尔。
