如何在Android中使用XML来使用资源阵列？(How to use resource array

我是新的Android开发，并面临着管理的Android资源的问题。 我想创建具有的ImageView和一个TextView一个ListView。

以下是我的实现，工作正常，但实际上我想用我之前创建这样的数组：

int[] img = getResources().getIntArray(R.Array.img);

package com.simplelistviewwithlistactivity;

import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ListView;

public class ListActivityS extends ListActivity {
    int[] img = { R.drawable.r1, R.drawable.r2, R.drawable.skycubemap1,
            R.drawable.skycubemap1, R.drawable.skycubemap2,
            R.drawable.skycubemap3, R.drawable.skycubemap4,
            R.drawable.skycubemap5 };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getListView().setDividerHeight(2);
        getListView().setAdapter(new BindDataAdapter(this, img, item));
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Builder builder = new AlertDialog.Builder(this);
        builder.setMessage(item[position] + " is clicked.");
        builder.setPositiveButton("OK", null);
        builder.show();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_list, menu);
        return true;
    }

    private String item[] = { "This is list Item1", "This is list Item2",
            "This is list Item3", "This is list Item4", "This is list Item5",
            "This is list Item6", "This is list Item8", "This is list Item8"

Answer 1:

创建一个XML像下面，并把它放在RES /价值/ arrays.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <array name="icons">
        <item>@drawable/home</item>
        <item>@drawable/settings</item>
        <item>@drawable/logout</item>
    </array>
    <array name="colors">
        <item>#FFFF0000</item>
        <item>#FF00FF00</item>
        <item>#FF0000FF</item>
    </array>
</resources>

然后，使用这样的代码：

Resources res = getResources();
TypedArray icons = res.obtainTypedArray(R.array.icons);
Drawable drawable = icons.getDrawable(0);

TypedArray colors = res.obtainTypedArray(R.array.colors);
int color = colors.getColor(0,0);

Answer 2:

您可以使用资源res/values/arrays.xml 。

对于可绘

<integer-array name="your_images">
    <item>@drawable/ic_active_image</item>
    <item>@drawable/ic_visited_image</item>
</integer-array>

val drawables = resources.obtainTypedArray(R.array.your_images)
val drawable = drawables.getResourceId(position, -1)
image.setImageResource(drawable)
drawables.recycle()

对于颜色

<array name="your_colors">
    <item>#365374</item>
    <item>#00B9FF</item>
</array>

val colors = resources.obtainTypedArray(R.array.your_colors)
val color = colors.getColor(position, -1)
title.setTextColor(color)
colors.recycle()

对于字符串

<string-array name="your_strings">
    <item>Active</item>
    <item>Visited</item>
</string-array>

val strings = resources.getStringArray(R.array.your_strings)
title.text = strings[position]

复数 ：

<plurals name="proposal_plurals">
    <item quantity="zero">No proposals</item>
    <item quantity="one">%1$d proposal</item>
    <item quantity="two">%1$d proposals</item>
    <item quantity="few">%1$d proposals</item>
    <item quantity="many">%1$d proposals</item>
    <item quantity="other">%1$d proposals</item>
</plurals>

val proposals = count.takeIf { it != 0 }?.let {
    resources.getQuantityString(R.plurals.proposal_plurals, it, it)
} ?: "No proposals available"
