我需要制作一个带有文本和图标的微调器。我该怎么做？我现在只是如何将相同的图标放在微调器的所有行上。我需要在每一行上放置不同的图标。

Answer 1

这是main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <Spinner android:id="@+id/spinner"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

这是textandicon.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <ImageView android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/icon"/>
    <TextView android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="ABC"/>
</LinearLayout>

这是 Activity :-

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Spinner;

public class SpinnerPractice extends Activity {
    Spinner spinner;
    LayoutInflater inflator;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        spinner = (Spinner) findViewById(R.id.spinner);
        spinner.setAdapter(new NewAdapter());
        inflator = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    class NewAdapter extends BaseAdapter {

        @Override
        public int getCount() {
            return 26;
        }

        @Override
        public Object getItem(int arg0) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            if (convertView == null) {
                convertView = inflator.inflate(R.layout.textandicon, null);
            }
            return convertView;
        }

    }
}

希望这对您有所帮助。
