应用程序失败，logcat说行29似乎没问题

这里是代码，第29行对应的bextras按钮配置，它似乎是正确的。第29行 - extras.setTypeface（font3）;当我删除它并启动应用程序时，它会转到extras.setOnClickListener并在那里显示错误，当我删除整个额外按钮及其道具（包括setOnClickListener）时，该应用程序正常工作。应用程序失败，logcat说行29似乎没问题

怎么了？

public class TheBeginning extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_the_beginning); 
    Button gogym = (Button) findViewById(R.id.bgym); 
    Typeface font = Typeface.createFromAsset(getAssets(), "Sanvito.ttf"); 
    gogym.setTypeface(font); 
    Button gofav = (Button) findViewById(R.id.bfav); 
    Typeface font1 = Typeface.createFromAsset(getAssets(), "Sanvito.ttf"); 
    gofav.setTypeface(font1); 
    Button goindex = (Button) findViewById(R.id.bindex); 
    Typeface font2 = Typeface.createFromAsset(getAssets(), "Sanvito.ttf"); 
    goindex.setTypeface(font2); 
    Button extras = (Button) findViewById(R.id.bextra1); 
    Typeface font3 = Typeface.createFromAsset(getAssets(), "Sanvito.ttf"); 
    **extras.setTypeface(font3);** //Line 29 
    TextView minit = (TextView) findViewById(R.id.minititle); 
    Typeface font4 = Typeface.createFromAsset(getAssets(), "Alba.TTF"); 
    minit.setTypeface(font4); 

    gogym.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Intent gogymint = new  Intent("com.irespekt.gymbook.GOTOgym"); 
      startActivity(gogymint); 
     } 
    }); 
    gofav.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Intent gofavint = new Intent("com.irespekt.gymbook.GOTOFAV"); 
      startActivity(gofavint); 
     } 
    }); 
    goindex.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Intent goindexint = new Intent(
         "com.irespekt.gymbook.INDEXPAGEACTIVITY"); 
      startActivity(goindexint); 
     } 
    }); 
    extras.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Intent extrasint = new Intent(
        "com.irespekt.gymbook.PICTUREVIEWFLIP"); 
      startActivity(extrasint); 
     } 
    }); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.the_beginning, menu); 
    return true; 
} 

}

您可以提供完整的LogCat以及定义了bextra1的布局xml吗？ – Grambot

请检查我的编辑 –

@TheCapn请检查我的编辑，它包含您所需要的一切，你是否能够找到任何东西？ –

MyBad ......对不起，我发现的错误。

带有id - bextra的按钮的id为gonow，现在我改变了activity_thebeginning.xml布局中的id，并且FORGOT重命名了其余的xlarge，xland等，导致了错误。

对不起，如果我给任何人头痛。感谢寿！

首先，你必须保持你的资产文件夹项目中，而不是内部

src然后，创建一个名为字体内资产的文件夹。然后，将特定的字体字体ttf文件放入其中。您可以在编码中使用字体字体，例如：

字体font = Typeface.createFromAsset（getAssets（），“fonts/Sanvito.ttf”）; gogym.setTypeface（font）;

有问题在下面的语句

Typeface font = Typeface.createFromAsset(getAssets(), "fonts/Sanvito.ttf");
