目标是实现以下功能。三个EditText字段。每个都应该用自定义键盘填充。 1.英语 俄罗斯人 转录
我在这个类的帮助下实现的键盘
public class CustomKeyboard {

和三种不同的xml-layouts
活动我创建三个键盘类副本。具有不同的布局。在他们的领域注册他们每个人。
public class WordsListActivity extends Activity {
public static final String LOG_TAG = "WordsListActivity";
protected RecyclerView mRecyclerView;
protected Button btnAddWord;
protected WordViewAdapter mAdapter;
protected RecyclerView.LayoutManager mLayoutManager;
protected WordsListActivity.LayoutManagerType mCurrentLayoutManagerType;
protected List<Word> wordsList;
protected int categoryId;
protected CustomKeyboard mCustomKeyboardEN, mCustomKeyboardRU, mCustomKeyboardTrancroption;
protected ForegroundLinearLayout addWordLyout;
protected Button okButton, cancelButton;
protected EditText etWordOrigin, etWordTranslate, etWordTranscription;
private enum LayoutManagerType {
GRID_LAYOUT_MANAGER,
LINEAR_LAYOUT_MANAGER
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_words_list);
Intent intent = getIntent();
categoryId = (int) intent.getLongExtra("categoryId",0);
View rootView = getLayoutInflater().inflate(R.layout.content_main, null).getRootView();
mRecyclerView = (RecyclerView)findViewById(R.id.wrodsRecyclerView);
btnAddWord = (Button)findViewById(R.id.btnAddNewWord);
mLayoutManager = new LinearLayoutManager(this);
mCurrentLayoutManagerType = WordsListActivity.LayoutManagerType.LINEAR_LAYOUT_MANAGER;
setRecyclerViewLayoutManager(mCurrentLayoutManagerType);
addWordLyout =(ForegroundLinearLayout)findViewById(R.id.inputWordLayout);
addWordLyout.setVisibility(View.INVISIBLE);
etWordOrigin = (EditText)findViewById(R.id.etWordOrigin);
etWordTranslate = (EditText)findViewById(R.id.etWordTranslate);
etWordTranscription = (EditText)findViewById(R.id.etWordTrancription);
okButton = (Button) findViewById(R.id.addButton);
cancelButton = (Button) findViewById(R.id.cancelButton);
/* creting keybords*/
mCustomKeyboardRU = new CustomKeyboard(this, R.id.keyboardviewWords, R.xml.kbd_ru);//russian
mCustomKeyboardRU.registerEditText(R.id.etWordOrigin);
mCustomKeyboardEN = new CustomKeyboard(this, R.id.keyboardviewWords, R.xml.kbd_en);//english
mCustomKeyboardEN.registerEditText(R.id.etWordTranslate);
/*in all EditText field showing this last keyboard copy*/
mCustomKeyboardTrancroption = new CustomKeyboard(this, R.id.keyboardviewWords, R.xml.kbd_transcription);//transcription
mCustomKeyboardTrancroption.registerEditText(R.id.etWordTrancription);
btnAddWord.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
addWordLyout.setVisibility(View.VISIBLE);
}
});
}
@Override public void onBackPressed() {
// NOTE Trap the back key: when the CustomKeyboard is still visible hide it, only when it is invisible, finish activity
if( mCustomKeyboardRU.isCustomKeyboardVisible() ) mCustomKeyboardRU.hideCustomKeyboard(); else this.finish();
}
public void setRecyclerViewLayoutManager(WordsListActivity.LayoutManagerType layoutManagerType) {
/*
mLayoutManager = new GridLayoutManager(this, SPAN_COUNT);
mCurrentLayoutManagerType = LayoutManagerType.GRID_LAYOUT_MANAGER;*/
mLayoutManager = new LinearLayoutManager(this);
mCurrentLayoutManagerType = WordsListActivity.LayoutManagerType.LINEAR_LAYOUT_MANAGER;
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.scrollToPosition(0);
initDataset();
}
private void initDataset() {
wordsList = new DataBase(this).getWordsList(categoryId);
mAdapter = new WordViewAdapter(wordsList, this);
mRecyclerView.setAdapter(mAdapter);
if(wordsList.size()==0){
Toast.makeText(this, "nothing to Show", Toast.LENGTH_LONG).show();
}
}
}
但是当您运行专注于所有字段的应用程序时，它会显示最后一个键盘。在这种情况下转录。
