일주일 동안 수수께끼를 푼 후. 내가 알아 낸 것 같아
툴바 내에서 EditText 만 사용하고 있습니다. 이것은 reddit에서 oj88에 의해 제안되었습니다.

나는 이제 이것을 가지고있다 :

먼저 내 활동의 onCreate () 내부에 오른쪽과 같이 이미지보기가있는 EditText를 툴바에 다음과 같이 추가했다 :

    // Setup search container view
    searchContainer = new LinearLayout(this);
    Toolbar.LayoutParams containerParams = new Toolbar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    containerParams.gravity = Gravity.CENTER_VERTICAL;
    searchContainer.setLayoutParams(containerParams);

    // Setup search view
    toolbarSearchView = new EditText(this);
    // Set width / height / gravity
    int[] textSizeAttr = new int[]{android.R.attr.actionBarSize};
    int indexOfAttrTextSize = 0;
    TypedArray a = obtainStyledAttributes(new TypedValue().data, textSizeAttr);
    int actionBarHeight = a.getDimensionPixelSize(indexOfAttrTextSize, -1);
    a.recycle();
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, actionBarHeight);
    params.gravity = Gravity.CENTER_VERTICAL;
    params.weight = 1;
    toolbarSearchView.setLayoutParams(params);

    // Setup display
    toolbarSearchView.setBackgroundColor(Color.TRANSPARENT);
    toolbarSearchView.setPadding(2, 0, 0, 0);
    toolbarSearchView.setTextColor(Color.WHITE);
    toolbarSearchView.setGravity(Gravity.CENTER_VERTICAL);
    toolbarSearchView.setSingleLine(true);
    toolbarSearchView.setImeActionLabel("Search", EditorInfo.IME_ACTION_UNSPECIFIED);
    toolbarSearchView.setHint("Search");
    toolbarSearchView.setHintTextColor(Color.parseColor("#b3ffffff"));
    try {
        // Set cursor colour to white
        // https://stackoverflow.com/a/26544231/1692770
        // https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564
        Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
        f.setAccessible(true);
        f.set(toolbarSearchView, R.drawable.edittext_whitecursor);
    } catch (Exception ignored) {
    }

    // Search text changed listener
    toolbarSearchView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            Fragment mainFragment = getFragmentManager().findFragmentById(R.id.container);
            if (mainFragment != null && mainFragment instanceof MainListFragment) {
                ((MainListFragment) mainFragment).search(s.toString());
            }
        }

        @Override
        public void afterTextChanged(Editable s) {
            // https://stackoverflow.com/a/6438918/1692770
            if (s.toString().length() <= 0) {
                toolbarSearchView.setHintTextColor(Color.parseColor("#b3ffffff"));
            }
        }
    });
    ((LinearLayout) searchContainer).addView(toolbarSearchView);

    // Setup the clear button
    searchClearButton = new ImageView(this);
    Resources r = getResources();
    int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 16, r.getDisplayMetrics());
    LinearLayout.LayoutParams clearParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    clearParams.gravity = Gravity.CENTER;
    searchClearButton.setLayoutParams(clearParams);
    searchClearButton.setImageResource(R.drawable.ic_close_white_24dp); // TODO: Get this image from here: https://github.com/google/material-design-icons
    searchClearButton.setPadding(px, 0, px, 0);
    searchClearButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            toolbarSearchView.setText("");
        }
    });
    ((LinearLayout) searchContainer).addView(searchClearButton);

    // Add search view to toolbar and hide it
    searchContainer.setVisibility(View.GONE);
    toolbar.addView(searchContainer);

이것은 효과가 있었지만 홈 버튼을 눌렀을 때 onOptionsItemSelected ()가 호출되지 않는 문제가 발생했습니다. 그래서 홈 버튼을 눌러 검색을 취소 할 수 없었습니다. 홈 버튼에 클릭 리스너를 등록하는 몇 가지 방법을 시도했지만 작동하지 않았습니다.

결국 나는 가지고 있던 ActionBarDrawerToggle이 물건을 방해하고 있다는 것을 알았으므로 그것을 제거했습니다. 이 리스너는 다음 작업을 시작했습니다.

    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // toolbarHomeButtonAnimating is a boolean that is initialized as false. It's used to stop the user pressing the home button while it is animating and breaking things.
            if (!toolbarHomeButtonAnimating) {
                // Here you'll want to check if you have a search query set, if you don't then hide the search box.
                // My main fragment handles this stuff, so I call its methods.
                FragmentManager fragmentManager = getFragmentManager();
                final Fragment fragment = fragmentManager.findFragmentById(R.id.container);
                if (fragment != null && fragment instanceof MainListFragment) {
                    if (((MainListFragment) fragment).hasSearchQuery() || searchContainer.getVisibility() == View.VISIBLE) {
                        displaySearchView(false);
                        return;
                    }
                }
            }

            if (mDrawerLayout.isDrawerOpen(findViewById(R.id.navigation_drawer)))
                mDrawerLayout.closeDrawer(findViewById(R.id.navigation_drawer));
            else
                mDrawerLayout.openDrawer(findViewById(R.id.navigation_drawer));
        }
    });

이제 홈 버튼으로 검색을 취소 할 수 있지만 뒤로 버튼을 눌러 취소 할 수는 없습니다. 그래서 이것을 onBackPressed ()에 추가했습니다.

    FragmentManager fragmentManager = getFragmentManager();
    final Fragment mainFragment = fragmentManager.findFragmentById(R.id.container);
    if (mainFragment != null && mainFragment instanceof MainListFragment) {
        if (((MainListFragment) mainFragment).hasSearchQuery() || searchContainer.getVisibility() == View.VISIBLE) {
            displaySearchView(false);
            return;
        }
    }

이 메소드를 작성하여 EditText 및 메뉴 항목의 가시성을 토글합니다.

public void displaySearchView(boolean visible) {
    if (visible) {
        // Stops user from being able to open drawer while searching
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

        // Hide search button, display EditText
        menu.findItem(R.id.action_search).setVisible(false);
        searchContainer.setVisibility(View.VISIBLE);

        // Animate the home icon to the back arrow
        toggleActionBarIcon(ActionDrawableState.ARROW, mDrawerToggle, true);

        // Shift focus to the search EditText
        toolbarSearchView.requestFocus();

        // Pop up the soft keyboard
        new Handler().postDelayed(new Runnable() {
            public void run() {
                toolbarSearchView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, 0, 0, 0));
                toolbarSearchView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, 0, 0, 0));
            }
        }, 200);
    } else {
        // Allows user to open drawer again
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);

        // Hide the EditText and put the search button back on the Toolbar.
        // This sometimes fails when it isn't postDelayed(), don't know why.
        toolbarSearchView.postDelayed(new Runnable() {
            @Override
            public void run() {
                toolbarSearchView.setText("");
                searchContainer.setVisibility(View.GONE);
                menu.findItem(R.id.action_search).setVisible(true);
            }
        }, 200);

        // Turn the home button back into a drawer icon
        toggleActionBarIcon(ActionDrawableState.BURGER, mDrawerToggle, true);

        // Hide the keyboard because the search box has been hidden
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(toolbarSearchView.getWindowToken(), 0);
    }
}

툴바의 홈 버튼을 서랍 아이콘과 뒤로 버튼 사이에서 전환하는 방법이 필요했습니다. 결국 이 SO 답변 에서 아래 방법을 찾았습니다 . 좀 더 이해하기 쉽게 약간 수정했지만 :

private enum ActionDrawableState {
    BURGER, ARROW
}

/**
 * Modified version of this, https://stackoverflow.com/a/26836272/1692770<br>
 * I flipped the start offset around for the animations because it seemed like it was the wrong way around to me.<br>
 * I also added a listener to the animation so I can find out when the home button has finished rotating.
 */
private void toggleActionBarIcon(final ActionDrawableState state, final ActionBarDrawerToggle toggle, boolean animate) {
    if (animate) {
        float start = state == ActionDrawableState.BURGER ? 1.0f : 0f;
        float end = Math.abs(start - 1);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            ValueAnimator offsetAnimator = ValueAnimator.ofFloat(start, end);
            offsetAnimator.setDuration(300);
            offsetAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
            offsetAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                @Override
                public void onAnimationUpdate(ValueAnimator animation) {
                    float offset = (Float) animation.getAnimatedValue();
                    toggle.onDrawerSlide(null, offset);
                }
            });
            offsetAnimator.addListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animation) {

                }

                @Override
                public void onAnimationEnd(Animator animation) {
                    toolbarHomeButtonAnimating = false;
                }

                @Override
                public void onAnimationCancel(Animator animation) {

                }

                @Override
                public void onAnimationRepeat(Animator animation) {

                }
            });
            toolbarHomeButtonAnimating = true;
            offsetAnimator.start();
        }
    } else {
        if (state == ActionDrawableState.BURGER) {
            toggle.onDrawerClosed(null);
        } else {
            toggle.onDrawerOpened(null);
        }
    }
}

이것은 효과가 있습니다. 나는 길을 따라 찾은 몇 가지 버그를 해결했습니다. 나는 그것이 100 %라고 생각하지 않지만 그것은 나를 위해 충분히 잘 작동합니다.
