使用方法

private void addressDialog() { AddressDialog addressDialog =new AddressDialog(); addressDialog.setOnSelectListener(new AddressDialog.OnSelectListener() { @Override public int getHeight() { return 0; } @SuppressLint("SetTextI18n") @Override public void onSelect(String province, String city, String area, String street) { tvPositionRtrCommunity.setText(province+" "+city+" "+area+" "+street); } @Override public void isMissing() { isShowDialog = true; } }); addressDialog.show(getSupportFragmentManager(),AddressDialog.class.getSimpleName());}
