Android-尝试更改活动时出错

Question

For some reason this came up when trying to switch activities. I've had no problem running the same kind of code with other activities in this project. I'll post the code and see if anyone can figure it out ;(

I can't get my error to format right in this, so here's the error log http://textuploader.com/oe6g

Here's my different activities.

The Problem occurs when I click on the button in my New Game Activity Layout, and that button runs the confirm(View view)

NewGameActivity.java

public class NewGameActivity extends Activity {
EditText title;
TextView team1, team2;
SqliteHelper db;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_newgame);
    //ListViews
    team1 = (TextView) findViewById(R.id.textView4);
    team2 = (TextView) findViewById(R.id.textView5);
    title = (EditText) findViewById(R.id.editText1);
    db = new SqliteHelper(this.getApplicationContext());
    populateListViews();
    registerClickCallback();
}

/*

private void populateListViews() {
    // THIS HERE WILL POPULATE BOTH TEAM LIST VIEWS
    //Create list of items
    Cursor cursor = db.getTeams();

    ArrayList<String> values = new ArrayList<String>();
    if (cursor != null && cursor.getCount() != 0) {
        cursor.moveToFirst();
        while (!cursor.isAfterLast()) {

            values.add(cursor.getString(cursor.getColumnIndex("Team_Names")));

            cursor.moveToNext();
        }
    }

</RelativeLayout>

I mean it tells me the error occurs in the onCreate of the CourtActivity, however I can't see anything that's wrong. This is part of my school project, I'm only concerned with the things that are causing me errors currently, not too worried about anything else.

Note:This is a group project. The courtactivity screen is the only one I've not had a part in making, so I'm not sure exactly what went into it. However now I'm trying to put everything together and running into this.

Anything helps! Thanks!

Answer 1

The error is coming from inflating the layout. It's an OutOfMemoryError. Do you have some really huge bitmap or more likely a circular dependency? Can you upload the xml file R.layout.activity_court?

Answer 2

The error is happening while attempting to load an image specified on the Layout file, as reported by the following part of the log:

...: Caused by: java.lang.OutOfMemoryError
...: E/AndroidRuntime(2137):    at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)
...: E/AndroidRuntime(2137):    at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:503)

I bet if you remove the line android:background="@drawable/bg2court" from the root container (RelativeLayout) in the file activity_court.xml the error will be gone. If that is the case I would suggest you to try a smaller (lower resolution) version of that image.
While looking for a replacement, keep an eye on the heap memory allocation messages on logcat so you will know how much progress you are making.

Loading high resolution images on Android is usually a tricky process because of the following reasons:

1. Bitmap files loaded in memory have to be decompressed so they can be rendered, making them a lot larger then their original .JPG and .PNG files. To calculate how many bytes of memory will be allocated to load a given image, just follow this simple formula: width ( pixels ) x height ( pixels ) x number bytes per pixel (3 for 24 bit images). Example: a bitmap with the size of 2048x2048 pixels takes exactly 12mb of memory;
2. Bitmaps are loaded into the heap space which happens to be a pretty small portion of memory given by the OS to your app when it starts. The size of the heap space usually ranges from 16 to 64mb depending on the device.

Finally, I would suggest one of the following approaches:

1. Replace the large background image by a lower resolution version that can be scaled up to fill the background space (at the cost of quality of corse);
2. Load bitmaps programmatically. There are BitmapFactory methods that can downsample images on the fly, during the load process. More on this here ;
3. Use a 3rd party library to do it for you. Picasso is an excelent choice.

Answer 3

I had this error no long ago but got some help from the guys in here

here is what I did

if your background / image don't need transpart stuff or like keep in JPG format as it will be smaller. this should sort your Out of Memory issue temp. but when you have more image coming up you will still have problem (Out of Memory) coming up again

hope this can help you for the time been
