在三星GT-N5110安卓版4.1.2中放大TextViews和Checkboxes时遇到问题 放大TextView后出现下面的图像里面的textview我想要扩展它我尝试在开发人员选项中启用缩放动画而没有使用我也尝试过nineoldandroid.jar。

enter image description here

这是我在代码内的代码:

@Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.test, container, false);
        linearLayout = (LinearLayout) view.findViewById(R.id.test);
        textView = (AutoResizeTextView) view.findViewById(R.id.text);
        return view;
    }


    @Override
        public void onStart() {
            super.onStart();
     ObjectAnimator.ofFloat(linearLayout , "scaleY", 500).setDuration(500).start();
        ObjectAnimator.ofFloat(linearLayout , "scaleX", 500).setDuration(500).start();
        }

布局:

 <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">


        <LinearLayout
            android:id="@+id/test"
            android:layout_width="30dp"
            android:layout_height="30dp"
            android:layout_gravity="center"
            android:background="@drawable/prayer_background">

            <com.example.views.AutoResizeTextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:text="@string/aboutUs"
                android:textSize="5sp" />

        </LinearLayout>
    </LinearLayout>

prayer_background:

<?xml version="1.0" encoding="utf-8"?>

    <shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="oval">
        <corners android:radius="10dip" />
        <stroke
            android:width="5dip"
            android:color="@color/mainColor" />
        <solid android:color="@color/mainColor" />
    </shape>

我确实尝试过AutoResizeText和ScaleableTextView here: 我得到以下结果: enter image description here

private int dp2px(float dp){
            return (int) (dp * activity.getResources().getDisplayMetrics().density + 0.5f);
        }
        private doScale(){
            final LinearLayout linearLayout = (LinearLayout) view.findViewById(R.id.test);
            final TextView textView = (TextView) linearLayout.findViewById(R.id.tv_main);
            final int oldSize = dp2px(30);
            final float scale = 2f;
            final float textSizeOld = textView.getTextSize();
            ValueAnimator valueAnimatorLarge = ValueAnimator.ofInt(1,100 );
            valueAnimatorLarge.setDuration(500);
            valueAnimatorLarge.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

                @Override
                public void onAnimationUpdate(ValueAnimator animation) {
                    ViewGroup.LayoutParams layoutParams = linearLayout.getLayoutParams();
                    float currentScale = (int)animation.getAnimatedValue()/100f;
                    layoutParams.width = (int) (scale*oldSize*currentScale);
                    layoutParams.height = layoutParams.width;
                    linearLayout.setLayoutParams(layoutParams);
                    textView.setTextSize(scale*textSizeOld*currentScale);
                }
            });
            valueAnimatorLarge.start();
        }
