Question

我创建了一个自定义的EditText，以便能够移动和调整EditText的大小。当我开始输入时，它正在我的手机上工作，但在其他手机上崩溃了。

当我将android:inputType="text"添加到Xml代码时，它工作但是应用程序的整个目的都丢失了这是完整的堆栈错误

这是XML代码

<RelativeLayout
            android:id="@+id/TextRoot"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <com.oluwayomi.quotage.custom.DragEditText
                android:id="@+id/etText"
                style="@style/Widget.AppCompat.Button.Borderless"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerHorizontal="true"
                android:layout_gravity="center"
                android:layout_marginTop="124dp"
                android:background="@drawable/null_background"
                android:gravity="center"
                android:padding="10dp"
                android:hint="Type text here.\n Double tap to edit \n and long press to resize."
                android:textSize="22sp" />
        </RelativeLayout>

以下是我的自定义EditText的代码

    public DragEditText(Context context) {
        this(context, null);

    }

    public DragEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        mPaintFrame = new Paint();
        mPaintTranslucent = new Paint();
        c = context;

        RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        this.setLayoutParams(layoutParams);
    }

    public DragEditText(Context context, AttributeSet attrs, int defStyleAttr) {
        this(context, attrs);

    }  @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        int viewWidth = MeasureSpec.getSize(widthMeasureSpec);
        int viewHeight = MeasureSpec.getSize(heightMeasureSpec);

        mParentWidth = c.getResources().getDisplayMetrics().widthPixels;
        mParentHeight = c.getResources().getDisplayMetrics().heightPixels;
        mParentRect = new RectF(0, 0, viewWidth, viewHeight);
    }
@Override

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

    }

Answer 1

在没有看到有用的解决方案的情况下进行搜索后，我终于发现了问题

style="@style/Widget.AppCompat.Button.Borderless"

无法应用EditText。

感谢大家。
