这是我的诀窍，
好处是一切都会如你所愿，
但不好的是它增加了布局层次结构，你必须在代码中处理功能，这是一个丑陋的解决方案：
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TextInputLayout
android:id="@+id/til"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/edt"
android:layout_width="match_parent"
android:layout_height="@dimen/edt_height"
android:hint="@string/create_gcc_visa_txt_step" />
</android.support.design.widget.TextInputLayout>
<Spinner
android:id="@+id/spn"
style="@style/MyAppTheme.Base.Spinner"
android:layout_height="@dimen/edt_height"
android:layout_alignBottom="@id/til" />
</RelativeLayout>
并覆盖微调器的适配器，以使所选值透明
public class MySpinnerAdapter extends SimpleAdapter {
Context mContext;
public MySpinnerAdapter(Context context, List<String> data, int resource, String[] from, int[] to) {
super(context, data, resource, from, to);
mContext = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = super.getView(position, convertView, parent);
TextView tv = (TextView) convertView.findViewById(android.R.id.text1);
tv.setTextColor(ContextCompat.getColor(mContext, R.color.transparent));
return convertView;
}
}
在微调器中选择后，只需获取选定的文本并将其设置为 EditText ，它将具有与动画相同的效果
yourSpinnerView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<String> adapterView, View view, int i, long l) {
//get your selected text from adapter or from where you want
String selectedText = adapterView.getItemAtPosition(i));
if (i != 0) {
edt.setText(selectedText);
} else {
// if in case your spinner have first empty text,
// then when spinner selected, just empty EditText.
edt.setText("");
}
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
