Question

我没有带下划线的代码，但只要我在模拟器上启动我的应用程序，就会收到这些错误。

public class SplashActivity extends AppCompatActivity {
    private TextView etSportisa;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
       /* ButterKnife.inject(this);
        mProgressBar.setIndeterminateDrawable(new foldingCirclesDrawable.Builder(this)
                .build());
        mProgressBar.setIndeterminateDrawable(new foldingCirclesDrawable.Builder(this)
                .colors(getResources().getIntArray(R.array.colors) //Array of 4 colors
                        .build()); */

        Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "fonts/esp_ital.ttf");
        etSportisa.setTypeface(myTypeFace);
        etSportisa = (TextView) findViewById(R.id.tv_sportisa);



        final ProgressDialog pd = new ProgressDialog(SplashActivity.this);
        pd.setMessage("Učitavanje...");
        pd.show();

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            public void run() {
                // Actions to do after 10 seconds
                pd.dismiss();

                Intent i = new Intent(SplashActivity.this, MainActivity.class);
                startActivity(i);
            }
        }, 2000);
    }
}

这是我的SplashActivity：

generics.ListAPIView

在assets \ font文件夹中添加特殊字体。我还为加载屏幕添加了一个图像，但我认为该字体是这些问题的表亲

Answer 1

对您的代码进行以下更改：

Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "fonts/esp_ital.ttf");
etSportisa = (TextView) findViewById(R.id.tv_sportisa);
etSportisa.setTypeface(myTypeFace);

初始化后，您可以使用任何布局进行任何操作。

Answer 2

问题在于：

etSportisa为空

在findViewByID

之后设置它

Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "fonts/esp_ital.ttf");
        etSportisa = (TextView) findViewById(R.id.tv_sportisa);
        etSportisa.setTypeface(myTypeFace);

试图在TextView上设置自定义字体 - nullpointer
