Answer 1

확인이 아웃 :

<ScrollView 
     android:id="@+id/sc" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" > 

     <TextView 
      android:id="@+id/mark" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_above="@+id/btn" 
      android:layout_below="@+id/txt" 
      android:ellipsize="marquee" 
      android:focusable="true" 
      android:focusableInTouchMode="true" 
      android:marqueeRepeatLimit="marquee_forever" 
      android:scrollHorizontally="true" 
      android:singleLine="true" 
      android:text="Thanks Christian but I am trying to get my text to scroll downwards automatically I am able to scroll horizontally fine." 
      android:textSize="50dp" /> 
    </ScrollView> 

<Button 
android:id="@+id/button" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="Scroll"/> 

활동 기록에서 다음은

ScrollView scrollView=(ScrollView) findViewById(R.id.sc); 
Button button=(Button) findViewById(R.id.button); 
button.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 
      scrollView.post(new Runnable() { 

     public void run() { 
      scrollView.smoothScrollTo(0, scrollView.getBottom()); 
     } 
    }); 
     } 
    });

Answer 3

시도해보십시오.

Animation animationToLeft = new TranslateAnimation(400, -400, 0, 0); 
animationToLeft.setDuration(12000); 
animationToLeft.setRepeatMode(Animation.RESTART); 
animationToLeft.setRepeatCount(Animation.INFINITE); 

Animation animationToRight = new TranslateAnimation(-400,400, 0, 0); 
animationToRight.setDuration(12000); 
animationToRight.setRepeatMode(Animation.RESTART); 
animationToRight.setRepeatCount(Animation.INFINITE); 

TextView textViewMarqToLeft = (TextView) findViewById(R.id.textViewMarqToLeft); 
TextView textViewMarqToRight = (TextView) findViewById(R.id.textViewMarqToRight); 

textViewMarqToLeft.setAnimation(animationToLeft); 
textViewMarqToRight.setAnimation(animationToRight); 
String textLeft = "Left marquue" 
String textRight = "Right marquue" 
textViewMarqToLeft.setText(textLeft); 
textViewMarqToRight.setText(textRight);
