关于EditText的onTextChange函数


TextWatcher txtEditWatcher = new TextWatcher() {
            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub                Log.e(LOGTAG, "List size    " + mStringList.size());
            }            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub
            }            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                // TODO Auto-generated method stub
                mIsChanged = true;
                if (DEBUG) {
                    Log.i(LOGTAG, "onTextChanged");
                }
                if (mTxtEdit.getHeight() <= mEditTextMinHeight) {
            Log.e(LOGTAG, "$$$$$$$$$$$$$$$$$$ reach min height!");
            if (mIndex + 1 < mLengthList) {
                mStringList.set(mIndex, mTxtEdit.getText()
                        + mStringList.get(mIndex + 1));
                mStringList.remove(mIndex + 1);
                mLengthList -= 1;
                int scrollY = mScrollview.getScrollY();
                // mTxtEdit.setText(mStringList.get(mIndex));
                mScrollview.setScrollY(scrollY);
                mHasEverChange = true;
                // setEditTextThread.start();
            } else {
                if (mTxtEdit.getText().toString().equals("")) {
                    if (mIndex - 1 >= 0) {
                        // If changed, then save the change to list
                        mStringList.remove(mIndex);
                        mLengthList -= 1;
                        mHasEverChange = true;
                        mIndex--;
                        // mTxtEdit.setText(mStringList.get(mIndex));
                        mIsChanged = false;
                        mScrollview.setScrollY(0);
                        // setEditTextThread.start();
                    }
                }
            }
        }
            }
        };
关键是onTextChanged里面还有个setText，它又会导致onTextChange的调用，这样会一直递推下去？请问有没有好的解决办法？我要在onTextChanged之后，调用setText，改变EditText上显示的文本。
