使用imageButtons切换活动。我如何切换图像的基础上按钮$ P $次活动pssed？ [英] Using imageButtons to switch activities. How can I switch image in second activity based on button pressed?

问题描述

我刚开始涉足与Android的发展。现在，我已经在Android的工作室，有大约每6幅图像的两列一个计划。我想使它所以如果我点击的形象，它会出现在新的活动。现在，我只是加载的布局是这样的：

I am just starting to dabble with Android development. Right now, I have a program in Android Studio that has two columns of images about 6 images each. I want to make it so if I click that image, it will appear in the new activity. Right now, I am just loading the layout like this:

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    String name = intent.getStringExtra(Main.CHAMPION_NAME);
    setContentView(R.layout.activity_champion_page);

}

随着的setContentView布局看起来像这样：

With the layout in setContentView looking like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="atree496.leaguestats.ChampionPage">


    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/azir"
        android:id="@+id/imageView" />
</LinearLayout>

截至目前，它打开了一个图像，因为那是它是如何设置的，但我希望能够有形象是我点击的人。我需要什么样的变化做才能实现这一目标？同样，我是新来这个。感谢您的帮助，你可以给。

As of now, it opens to the one image because that is how it is set up, but I want to be able to have the image be the one that I click. What changes do I need to do in order to achieve this? Again, I am new to this. Thank you for any help you can give.

推荐答案

您可以添加您的pressed形象的意图INT资源，如果你给它的文件名标签中的XML属性：

You could add to the intent the int resource of your pressed image if you give it file name to Tag attribute in xml:

ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/azir"
android:tag="theImageFileName.png"
android:id="@+id/imageView" />

然后，你可以retreive它时，pressed并将其添加到您正在使用的意图：

Then you could retreive it when pressed and add it to the Intent you are using:

 @Override
 public void onClick(View v) {
     String fileName = (String) v.getTag();
     Intent intent = new Intent(this, SecondActivity.class);
     intent.putExtra("fileName", fileName);
      startActivity(intent);
 }

在第二个活动在初始化secondImageView后：

In second activity after you initialize the secondImageView:

String fileName = getIntent().getStringExtra("fileName");
int resId = getResources().getIdentifier(fileName,"drawable", getPackageName());
secondImage.setImageDrawable(getResources().getDrawable(resId));
