我在启动此活动时收到此异常：

我已尝试（如在其他解决方案中发布的那样）清除项目，但没有任何反应。页面的代码很简单：

public class NoAccountPage extends Activity {

    private boolean doubleBackToExitPressedOnce;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Rimuovo la barra del titolo
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        // Impedisco al layout di girarsi se giro il device
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        // Carico il layout
        setContentView(R.layout.no_account_page);

        // ##########################
        // ##  Gestione dei Fonts  ##
        // ##########################

        TextView textSlab = (TextView) findViewById(R.id.SlabText);
        Typeface fontSlab = Typeface.createFromAsset(getAssets(), "fonts/RobotoSlab-Regular.ttf");
        textSlab.setTypeface(fontSlab);
        TextView textCondensed = (TextView) findViewById(R.id.CondensedText);
        Typeface fontCondensed = Typeface.createFromAsset(getAssets(), "fonts/RobotoCondensed-Regular.ttf");
        textCondensed.setTypeface(fontCondensed);
    }

    // Abilito l'uscita dall'app in caso di DOUBLE-BACK

    @Override
    public void onBackPressed() {
        if(doubleBackToExitPressedOnce) {
            super.onBackPressed();
            return;
        }

        this.doubleBackToExitPressedOnce = true;
        Toast.makeText(this, getString(R.string.pressTwiceToExit), Toast.LENGTH_SHORT).show();
        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                doubleBackToExitPressedOnce = false;
            }
        }, 2000);

    }
}

文件的声明出现在 MANIFEST 中。布局是现有和工作布局的副本。可能是什么问题？

谢谢！！

【问题讨论】：

Binary XML file line #2: You must supply a layout_width attribute. 你在 xml 文件上有一个错误，修复它，你已经删除了 xml 文件上的 layout_width，将 android:layout_width="match_parent" 添加到 xml 文件的第 2 行
尝试完整阅读日志跟踪，而不仅仅是第一行。

标签： android exception

【解决方案1】：

显示此错误是因为您错过了布局 no_account_page.xml 上的 set layout_width。

android:layout_width="match_parent"

或

android:layout_width="wrap_content"

【解决方案2】：

我已经尝试了所有给出的解决方案，是的 einschnaehkeee 我不仅阅读了第一行。谢谢咕噜。我已经解决了在 MANIFEST 中添加 INTENT-FILTER 的问题。我不知道为什么，但在那之后软件现在运行良好......无论如何，谢谢大家！
