指定鍵盤類型

android:inputType = "phone | textPassword | textMultiLine | text" android:imeOptions="actionSend | actionSearch | actionDone | actionGo" EditText editText = (EditText) findViewById(R.id.search);//顯示密碼框內(nèi)容 editText.setInputType(InputType.TYPE_CLASS_TEXT | EditorInfo.TYPE_TEXT_VARIATION_NORMAL); //隱藏密碼框內(nèi)容 editText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD); editText.setImeOptions(EditorInfo.IME_ACTION_GO);//設(shè)置光標(biāo)位置在文本框末尾 editText.setSelection(mEditPwd.getText().toString().length());//show the password editText.setTransformationMethod(HideReturnsTransformationMethod.getInstance()); //hide the password editText.setTransformationMethod(PasswordTransformationMethod.getInstance());editText.setOnEditorActionListener(new OnEditorActionListener() {@Overridepublic boolean onEditorAction(TextView v, int actionId, KeyEvent event) {boolean handled = false;if (actionId == EditorInfo.IME_ACTION_SEND) {sendMessage();handled = true;}return handled;} });

將輸入到 EditText 中的小寫字母轉(zhuǎn)化為大寫字母

//----------------小寫轉(zhuǎn)化為大寫--------------------------//public class InputLowerToUpper extends ReplacementTransformationMethod{ @Override protected char[] getOriginal() { char[] lower = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z' }; return lower; } @Override protected char[] getReplacement() { char[] upper = { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z' }; return upper; } } final EditText textCarNumber=(EditText) viewNew.findViewById(R.id.borrow_carnumber);textCarNumber.setTransformationMethod(new InputLowerToUpper());

在Activity啟動時顯示輸入法

android:windowSoftInputMode="stateVisible"

InputMethodManager

public void showSoftKeyboard(View view) {if (view.requestFocus()) {InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);imm.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);} }

指定 UI 的響應(yīng)方式

android:windowSoftInputMode = "adjust" android:windowSoftInputMode="adjustResize"

處理單個按鍵事件

@Override public boolean onKeyUp(int keyCode, KeyEvent event) {switch (keyCode) {case KeyEvent.KEYCODE_D:moveShip(MOVE_LEFT);return true;case KeyEvent.KEYCODE_F:moveShip(MOVE_RIGHT);return true;case KeyEvent.KEYCODE_J:fireMachineGun();return true;case KeyEvent.KEYCODE_K:fireMissile();return true;default:return super.onKeyUp(keyCode, event);} }

處理修飾鍵

@Override public boolean onKeyUp(int keyCode, KeyEvent event) {switch (keyCode) {...case KeyEvent.KEYCODE_J:if (event.isShiftPressed()) {fireLaser();} else {fireMachineGun();}return true;case KeyEvent.KEYCODE_K:if (event.isShiftPressed()) {fireSeekingMissle();} else {fireMissile();}return true;default:return super.onKeyUp(keyCode, event);} }
