splashactivity.java显示错误

Question

我的splashanimation.java文件存在问题。它不断在setcontentview和loadanimation上抛出错误。如果有人能指出我正在解决这个问题的正确方向，那将非常感激。

我还尝试清理项目以及删除问题错误。似乎没什么用。

我提前道歉，我仍然是Java世界的新手。

这是java文件。

package com.android.club;

public class ClubSplashActivity extends ClubActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);
        startAnimating();
    }



    private void startAnimating() {
        // Fade in top title
        TextView TextViewTopTitle = findViewById(R.id.TextViewTopTitle);
        Animation fade1 =  AnimationUtils.loadAnimation(this, R.anim.fade_in);
        TextViewTopTitle.startAnimation(fade1);

        // Fade in bottom title after a built-in delay.
        TextView TextViewbottomTitle = findViewById(R.id.TextViewbottomTitle);
        Animation fade2 = AnimationUtils.loadAnimation(this, R.anim.fade_in2);
        TextViewbottomTitle.startAnimation(fade2);


        fade2.setAnimationListener(new AnimationListener() {

            @Override
            public void onAnimationEnd(Animation animation) {

                startActivity(new Intent());
                ClubSplashActivity.this.finish();
            }

            @Override
            public void onAnimationRepeat(Animation animation) {
            }

            @Override
            public void onAnimationStart(Animation animation) {
            }
        });


        Animation spinin = AnimationUtils.loadAnimation(this, R.anim.custom_anim);
        LayoutAnimationController controller = new LayoutAnimationController(spinin);

        TableLayout table = (TableLayout) findViewById(R.id.TableLayout01);
        for (int i = 0; i < table.getChildCount(); i++) {
            TableRow row = (TableRow) table.getChildAt(i);
            row.setLayoutAnimation(controller);
        }

    }

    protected void startActivity(Intent intent) {
        // TODO Auto-generated method stub

    }

    protected void finish() {
        // TODO Auto-generated method stub

    }

    private TextView findViewById(int textviewtoptitle) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected void onPause() {
        super.onPause();

        TextView logo1 = findViewById(R.id.TextViewTopTitle);
        logo1.clearAnimation();

        TextView logo2 = findViewById(R.id.TextViewbottomTitle);
        logo2.clearAnimation();

        TableLayout table = (TableLayout) findViewById(R.id.TableLayout01);
        for (int i = 0; i < table.getChildCount(); i++) {
            TableRow row = (TableRow) table.getChildAt(i);
            row.clearAnimation();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();

        startAnimating();
    }

}

这是来自调试的logcat数据。如果这不是正确的信息我道歉。
