在 Android 程序里显示自己的图片

在Android程序里显示自己的图片

1. 定义文件flybulllogo.png于目录resdrawable下

2. 将main.xml改为如下即可

<?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"
　 >

<ImageView id="@+id/logo"
　 android:src="@drawable/flybulllogo"
　 android:layout_width="wrap_content"
　 android:layout_height="wrap_content"
　 />

</LinearLayout>

// 而直接在程序里面加载图片的方法如下

package com.flybull.pub;

import android.app.Activity;

import android.content.Context;

import android.os.Bundle;

import android.widget.ImageView;

public class pubBull extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

ImageView img = new ImageView(this);

img.setImageResource(R.drawable.flybulllogo);

setContentView(img);

}

}

// 更进一步, 变换图片

package com.flybull.pub;

import android.app.Activity;

import android.os.Bundle;

import android.widget.ImageView;

public class pubBull extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

ImageView img = new ImageView(this);

img.setImageResource(GeneratePicId());
