以下是我使用的相关代码。
自定义字体
这个的诀窍是我必须在我的Activity中将我的字体设置为mAutoCompleteTextView和tvAutocompleteListItem。
删除阴影
我将mAutoCompleteTextView的背景设置为R.drawable.autocomplete_dropdown。在那个drawable中,重要的一行是
<stroke
android:width="0dip"
android:color="@color/cp_green" />
<强>半径强>
半径在R.drawable.autocomplete_dropdown中设置如下:
<corners
android:radius="20dip"/>
<强> MainActivity.java 强>
private void setAutoCompleteListener() {
mAutoCompleteTextView.setDropDownBackgroundDrawable(
mContext.getResources().getDrawable(R.drawable.autocomplete_dropdown));
mAutoCompleteTextView.setAdapter(
new AutoCompleteAdapter(mContext, R.layout.autocomplete_list_item, mLatLng));
mAutoCompleteTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String autoCompleteText = (String) adapterView.getItemAtPosition(i);
mAutoCompleteTextView.setText(autoCompleteText);
initiateSearch();
hideKeyboard();
}
});
mAutoCompleteTextView.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i2, int i3) {
}
@Override
public void afterTextChanged(Editable editable) {
if (editable.length() > 0) {
mClearTextIcon.setVisibility(View.VISIBLE);
} else {
mClearTextIcon.setVisibility(View.INVISIBLE);
}
}
});
}
public void applyFonts() {
Log.d(TAG, "Applying Fonts.");
FontHelper.applyFont(findViewById(R.id.rlMap), mContext);
font = Font.getInstance(getApplicationContext());
mAutoCompleteTextView.setTypeface(font.mAvenirLTStandardLight);
LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.autocomplete_list_item, null);
TextView tvAutocompleteListItem = (TextView) view.findViewById(R.id.tvAutocompleteListItem);
tvAutocompleteListItem.setTypeface(font.mAvenirLTStandardLight);
}
