問題描述
我正在開發(fā)一個簡單的應用程序.剛剛完成主屏幕.如果方向變化超過兩次，則拋出錯誤，應用程序強制關閉.
I am developing a simple app. Just finished the home screen. If the orientation changes more than two times, it is throwing the error and application is force closing.
public class PasswordActivity extends Activity implements OnClickListener {
Button login;
Button forgot;
Button register;
private static final String PREFERENCES = "prefs";
private static final String PREFERENCES_NAME = "pref_name";
SharedPreferences settings;
private Cursor c;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
login=(Button)findViewById(R.id.login_login);
login.setOnClickListener(this);
register=(Button)findViewById(R.id.login_register);
register.setOnClickListener(this);
}
public void onClick(View v) {
}
}
我的 XML 代碼:

圖片非常小，大約 5kb.
Images are of very small size around 5kb.
推薦答案
在運行時，Android 根據(jù)需要(基于屏幕大小和分辨率)調整圖像大小.它使用位圖在內部進行大小調整.顯然，這非常占用內存(有點像瘋了一樣分配內存).解決此類問題的一種快速方法是將所有可繪制文件復制到 drawable-ldpi、mdpi、hdpi 文件夾.這樣，android 只會從這些文件夾中提取文件，而不是調整它們的大小.
At runtime, Android resize's images based on need (based on the screen size and resolution). It uses Bitmap's for doing the resizing internally. Which, obviously, is very memory intensive (kinda allocates memory like crazy). One quick way to fix such issues can be, that you copy all drawable files to drawable-ldpi, mdpi, hdpi folders. This way android will just pick up the files from these folders and not resize them.
這是一個隨機的異常，修復起來真的很痛苦.
Its a random kind exception, a real pain to fix.
