Question

我只字不提。我愿在上建立<代码>>ImageView,在一系列<代码>上的图像上打上<<<>Drawables。我愿对<代码>ImageView的图像,可以通过查阅mImages[position]检索。

Here is a brief explanation (complete explanation below): In short- I need a way to pass an image from my main activity to a dialog then on Cancel dismiss the dialog and on confirm set the system wallpaper (to the image passed from the main activity) then finish(); the activity.

此处作完整解释:

用户名单见Gallery和,高于Gallery,这表明对上重点的图像进行了较大的审查。彩虹/代码。



在<代码>Gallery上展示的图像使用:

        // setup wallpaper array
private void findWallpapers() {
    mThumbs = new ArrayList<Integer>(24);
    mImages = new ArrayList<Integer>(24);

    final Resources resources = getResources();
    final String packageName = getApplication().getPackageName();

    addWallpapers(resources, packageName, R.array.wallpapers);
}

// setup array defining all wallpapers & define thumbnails
private void addWallpapers(Resources resources, String packageName, int list) {
    final String[] extras = resources.getStringArray(list);
    for (String extra : extras) {
        int res = resources.getIdentifier(extra, "drawable", packageName);
        if (res != 0) {
            final int thumbRes = resources.getIdentifier(extra + "_small",
                    "drawable", packageName);

            if (thumbRes != 0) {
                mThumbs.add(thumbRes);
                mImages.add(res);
            }
        }
    }
}

在“Set Wallpaper”Button上报后,AlertDialog应当与另一个版面图相提并存,该图文在Gallery上。将包含一个<编码>TextView,附有指示、我们提议作为挂图、“Okay”代码和“Cancel”Button 的图像简介。发布“Okay”Button时,将把图像从>ImageViewpreview上贴在系统挂图上。 InputStream。

再次感谢!

    private void selectWallpaper(int position) {
    Toast.makeText(getBaseContext(), "Select Wallpaper", Toast.LENGTH_SHORT)
            .show();

    if (mIsWallpaperSet) {
        return;
    }

    mIsWallpaperSet = true;

    Context context = this;
    // CharSequence text = "Wallpaper Set!";
    // int duration = Toast.LENGTH_LONG;
    InputStream stream = getResources().openRawResource(
            mImages.get(position));
            final Dialog accept = new Dialog(context);
    accept.setContentView(R.layout.confirm);
    accept.setTitle("Please Confirm");
    TextView instructions = (TextView) accept.findViewById(R.id.textView1);
    instructions.setText("Would you like to set this as your wallpaper?");
    ImageView wallpreview = (ImageView) accept
            .findViewById(R.id.imageView1);
    wallpreview.createFromStream(stream, "test");
    // SETUP cancel (no btn) listener
    Button cancelbtn = (Button) accept.findViewById(R.id.button2);
    cancelbtn.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            accept.dismiss();
        }
    });
    // SETUP Yes Btn listener
    Button okbtn = (Button) accept.findViewById(R.id.button1);
    okbtn.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            // dismiss being used as placeholder, actually setting wallpaper
            // will be added
            accept.dismiss();
        }
    });
    accept.show();
}

{
    ;
}

您可以使用排外器,打破你的警惕性方言布局,并在你的主要活动中将其置于警示的视角。你们可以利用第ById()号来为这些县安排ClickListeners听众。这将确保你在ClickListener能够看到哺乳。

final ArrayList<Integer> mImages=new ArrayList<Integer>();
final ImageView v=findViewById(R.id.imageView);

AlertDialog d=new AlertDialog.Builder(Main.this).create();
d.setView(getLayoutInflater().inflate(R.layout.dialogView,findViewById(R.id.ROOT_LAYOUT_IN_XML_ID),false));

((ImageView)d.findViewById(R.id.YOUR_VIEW_ID)).setImageResource(mImages.get(?));

((Button)d.findViewById(R.id.cancelButton)).setOnClickListener(new OnClickListener()
{
    d.dismiss();
});
((Button)d.findViewById(R.id.acceptButton)).setOnClickListener(new OnClickListener()
{
    v.setImageResource(mImages.get(?));
    d.dismiss();
});
