标签： java android

请帮帮我。我已经尝试了一切，但无法解决这个问题。模拟器正在提示“应用程序名称不断停止”。我的API等级是28。谢谢您。

MainActivity.java

public class MainActivity extends AppCompatActivity {

    Button btnSignIn,btnSignUp;
    TextView txtslogan;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnSignIn = findViewById(R.id.btnSignIn);
        btnSignUp = findViewById(R.id.btnSignUp);

        txtslogan = findViewById(R.id.txtslogan);
        Typeface face = Typeface.createFromAsset(getAssets(),"fonts/Pacifico.ttf");
        txtslogan.setTypeface(face);

        btnSignIn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }

“在com.example.testrun.MainActivity.onCreate（MainActivity.java:20）处”-logcat中的这一行是蓝色的。

2 个答案:

答案 0 :(得分：0)

在布局xml中似乎为FBbutton取消了颜色。

Can't convert value at index 1 to color: type=0x5 at 
android.content.res.TypedArray.getColor(TypedArray.java:482)

您应该检查那些。也许先删除所有颜色属性，然后再添加一个以找出罪魁祸首。

答案 1 :(得分：0)

显然，这是您正在使用的库中的错误：

https://github.com/hoang8f/android-flat-button/issues/41

根据问题的评论，此问题仍未解决。 但是似乎有人分叉了库并对其进行了修复。 因此，您应该尝试使用此代替：
