我有CustomLayout,它有TextView,我在其上设置文本和可绘制编程但是问题是当我设置drawable时它添加了一个巨大的填充,我想要的是可绘制的更多在中心而不是在顶部
自定义ViewGroup
public class ProfileGridView extends FrameLayout {
public ProfileGridView(@NonNull Context context) {
super(context);
initView(context,null);
}
public ProfileGridView(@NonNull Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
initView(context,attrs);
}
public ProfileGridView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initView(context,attrs);
}
@TargetApi(21)
public ProfileGridView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
initView(context,attrs);
}
public void initView(Context context, AttributeSet attrs) {
TextView gridTextView;
View view = inflate(context, R.layout.square_grid, null);
gridTextView = (TextView) view.findViewById(R.id.grid_description);
TypedArray array = context.obtainStyledAttributes(attrs, R.styleable.ProfileGridView);
Drawable drawable = array.getDrawable(R.styleable.ProfileGridView_drawble);
String description = array.getString(R.styleable.ProfileGridView_grid_description);
gridTextView.setText(description);
gridTextView.setCompoundDrawablesWithIntrinsicBounds(null, drawable, null, null);
addView(view);
array.recycle();
}
}
CustomView LayoutFile
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/grid_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawablePadding="8dp"
android:gravity="center"
android:padding="0dp"
android:textSize="20sp" />
MainActivit.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.views.ProfileGridView
android:layout_width="200dp"
android:layout_height="200dp"
app:drawble="@drawable/ic_message"
app:grid_description="Message"/>
</RelativeLayout>

这不是填充问题,是因为您将可绘制的宽度和高度设置为200dp
你能使用&#34; wrap_content&#34;在drawable文件中?
如果不是只有一个图像文件并将其设置为TextView的可绘制

你能使用像这样的CustomView LayoutFile吗?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<ImageView
android:id="@+id/image"
android:layout_width="52dp"
android:layout_height="52dp" />
<TextView
android:id="@+id/grid_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="4dp"
android:textSize="20sp"/>
</LinearLayout>
并像这样设置drawable
ImageView image;
image = (ImageView) view.findViewById(R.id.image);
image.setImageDrawable(drawable);
而不是
gridTextView.setCompoundDrawablesWithIntrinsicBounds(null, drawable, null, null);
修改强>
正如您所问,您可以使用ProfileGridView wrap_content而不是200dp。使用setCompoundDrawablesWithIntrinsicBounds将drawable附加到TextView(200dp)的边界。 [您可以查看文档以获取更多信息](https://developer.android.com/reference/android/widget/TextView.html#setCompoundDrawablesWithIntrinsicBounds(android.graphics.drawable.Drawable,android.graphics.drawable.Drawable,android.graphics.drawable.Drawable,android.graphics.drawable.Drawable))
