嗨,我正在尝试制作我的第一个

Android应用程序,我做了一个闪屏.但是,我尝试添加加载请在底部等待,每2秒增加一次.我不确定如何实现它,因为屏幕因为这个文本崩溃了.

final TextView loadingText = (TextView)findViewById(R.id.loading_text);

Thread splashTimer = new Thread(){

public void run(){

try{

int splashTime = 0;

while(splashTime < 6000){

sleep(100);

if(splashTime < 2000){

loadingText.setText("Loading.");

}

else if(splashTime >= 2000 && splashTime < 4000 ){

loadingText.setText("Loading..");

}else if (splashTime >= 4000){

loadingText.setText("Loading...");

}

splashTime = splashTime + 100;

}

Intent intent = new Intent(MainActivity.this,myMainScreen.class);

startActivity(intent);

}catch(InterruptedException e){

e.printStackTrace();

}

finally{

finish();

}

}

};

splashTimer.start();

}

这是我的logcat
