關於如何能獲取到光標的時候 又不彈出系統軟鍵盤java
首先android
2.自定義EditText輸入框控件ide
這時 你會發現,光標是出來了 可是輸入文字,光標永遠在前面,怎麼辦,解決思路,監聽文字文本內容變化監聽方法,在afterTextChanged文字輸入完後,把光標移到最後.setSelection(Edittext,Edittext.length());動畫
package com.hatai.smartlokey.utils.edietext; import android.content.Context; import android.graphics.drawable.Drawable; import android.text.Editable; import android.text.TextWatcher; import android.util.AttributeSet; import android.view.MotionEvent; import android.view.View; import android.view.View.OnFocusChangeListener; import android.view.animation.Animation; import android.view.animation.CycleInterpolator; import android.view.animation.TranslateAnimation; import android.widget.EditText; import com.hatai.smartlokey.R; /** * Created by administrato on 2017-11-03. */ public class ClearEditText extends EditText implements OnFocusChangeListener, TextWatcher { /** * 刪除按鈕的引用 */ private Drawable mClearDrawable; /** * 控件是否有焦點 */ private boolean hasFoucs; public ClearEditText(Context context) { this(context, null); } public ClearEditText(Context context, AttributeSet attrs) { //這裏構造方法也很重要,不加這個不少屬性不能再XML裏面定義 this(context, attrs, android.R.attr.editTextStyle); } public ClearEditText(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); init(); } private void init() { //獲取EditText的DrawableRight,假如沒有設置咱們就使用默認的圖片 mClearDrawable = getCompoundDrawables()[2]; if (mClearDrawable == null) { // throw new NullPointerException("You can add drawableRight attribute in XML"); mClearDrawable = getResources().getDrawable(R.drawable.phone); } mClearDrawable.setBounds(0, 0, mClearDrawable.getIntrinsicWidth(), mClearDrawable.getIntrinsicHeight()); //默認設置隱藏圖標 setClearIconVisible(false); //設置焦點改變的監聽 setOnFocusChangeListener(this); //設置輸入框裏面內容發生改變的監聽 addTextChangedListener(this); } /** * 由於咱們不能直接給EditText設置點擊事件,因此咱們用記住咱們按下的位置來模擬點擊事件 * 當咱們按下的位置 在 EditText的寬度 - 圖標到控件右邊的間距 - 圖標的寬度 和 * EditText的寬度 - 圖標到控件右邊的間距之間咱們就算點擊了圖標,豎直方向就沒有考慮 */ @Override public boolean onTouchEvent(MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_UP) { if (getCompoundDrawables()[2] != null) { boolean touchable = event.getX() > (getWidth() - getTotalPaddingRight()) && (event.getX() < ((getWidth() - getPaddingRight()))); if (touchable) { this.setText(""); } } } return super.onTouchEvent(event); } /** * 當ClearEditText焦點發生變化的時候,判斷裏面字符串長度設置清除圖標的顯示與隱藏 */ @Override public void onFocusChange(View v, boolean hasFocus) { this.hasFoucs = hasFocus; if (hasFocus) { setClearIconVisible(getText().length() > 0); } else { setClearIconVisible(false); } } /** * 設置清除圖標的顯示與隱藏,調用setCompoundDrawables爲EditText繪製上去 * @param visible */ protected void setClearIconVisible(boolean visible) { Drawable right = visible ? mClearDrawable : null; setCompoundDrawables(getCompoundDrawables()[0], getCompoundDrawables()[1], right, getCompoundDrawables()[3]); } /** * 當輸入框裏面內容發生變化的時候回調的方法 */ @Override public void onTextChanged(CharSequence s, int start, int count, int after) { if(hasFoucs){ setClearIconVisible(s.length() > 0); } } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable s) { } /** * 設置晃動動畫 */ public void setShakeAnimation(){ this.setAnimation(shakeAnimation(5)); } /** * 晃動動畫 * @param counts 1秒鐘晃動多少下 * @return */ public static Animation shakeAnimation(int counts){ Animation translateAnimation = new TranslateAnimation(0, 10, 0, 0); translateAnimation.setInterpolator(new CycleInterpolator(counts)); translateAnimation.setDuration(1000); return translateAnimation; } }
1.會實現效果,可是會致使光標也沒法顯示,若是想顯示光標,你就須要定義一個方法,在方法內setInputType(禁止)ui
package com.hatai.smartlokey.utils.edietext; import android.text.InputType; import android.widget.EditText; import java.lang.reflect.Method; /** * Created by administrato on 2017-11-03. */ public class ShowEdietext { public static void disableShowInput(EditText editText){ if (android.os.Build.VERSION.SDK_INT <= 10){ editText.setInputType(InputType.TYPE_NULL); }else { Class<EditText> cls = EditText.class; Method method; try { method = cls.getMethod("setShowSoftInputOnFocus",boolean.class); method.setAccessible(true); method.invoke(editText,false); }catch (Exception e) {//TODO: handle exception } try { method = cls.getMethod("setSoftInputShownOnFocus",boolean.class); method.setAccessible(true); method.invoke(editText,false); }catch (Exception e) {//TODO: handle exception } } } }
et_qujian_phone_send.setOnFocusChangeListener(new View.OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { disableShowInput(et_qujian_phone_send); numPan.bindEditText(et_qujian_phone_send); } });
1,初次進入隱藏軟鍵盤(多種方式)this
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
2,點擊EditText獲取焦點,但不彈出軟鍵盤.net
public static void setDontShowSoftInputWhenFocused(EditText editText) { try { Method setShowSoftInputOnFocus = editText.getClass().getMethod("setShowSoftInputOnFocus", boolean.class); setShowSoftInputOnFocus.setAccessible(true); setShowSoftInputOnFocus.invoke(editText, false); } catch (Exception e) { e.printStackTrace(); } }
