java - 尝试更改字体时出现 Digitalclock 运行时错误

Question

我试图在 Activity 中显示数字时钟，但是当我添加更改字体的代码时，应用程序崩溃了:

注意:字体在asset文件夹中，名称正确

package asd.asasdx;

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.widget.DigitalClock;

public class ClockzActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        DigitalClock digitalClock = (DigitalClock) findViewById(R.id.digitalClock);
        setContentView(R.layout.main);
        Typeface type = Typeface.createFromAsset(getAssets(), "DS_DIGI.TTF");
        digitalClock.setTypeface(type);
    }
}

和 XML:

<DigitalClock
    android:id="@+id/digitalClock"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:text="DigitalClock"
    android:textSize="70dp"
    android:textColor="#00FF00"
    android:gravity="center"
    android:shadowColor="#00FF00"
    android:shadowRadius="16" />

但是当我运行该应用程序时，它会因为运行时错误而崩溃:

有什么问题？

Answer 1

您的代码是正确的，但只有当我们遇到任何与字体相关的问题时才会出现此错误，因此请检查您的字体位置和字体名称可能不相同或字体中的任何其他问题。
