I have two EditTexts and one CheckBox and a Button in my layout in the above order. After entering the values to the EditText, the user has to accept terms and conditions by clicking the Checkbox. I need to remove focus from EditTexts after the checkbox is clicked. Right now the focus is always on the second EditText. How can this be achieved? Please help. Layout:

推荐答案

使用Check Box中的onCheckedChangeListener，您可以执行此操作.只需将其应用于您的Activity's onCreate()

Using onCheckedChangeListener of Check Box you can do this. Just apply this on your Activity's onCreate()

chb1 = (CheckBox) findViewById(R.id.pm_check_t_and_c);
        chb1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (chb1.isChecked()) {
                    edt1.clearFocus();
                    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(edt1.getWindowToken(), 0);
                } else {
                    edt1.requestFocus();
                }

            }
        });
