Question

如何才能点击EditText的右侧绘图（查看屏幕截图）？我尝试过几种方法，但总是卡住了。

public static Matcher<View> withEditTextDrawable(final int resourceId) {
    return new BoundedMatcher<View, EditText>(EditText.class) {
        @Override
        protected boolean matchesSafely(final EditText editText) {
            // ????

            return false;
        }

        @Override
        public void describeTo(Description description) {
            description.appendText("with drawable from resource id: ");
            description.appendValue(resourceId);
        }
    };
}

Answer 1

必须开发此自定义操作和匹配器来测试某些文本字段右侧的丢弃抽屉，这将在Espresso测试中点击TextView的任何可绘制的（左，上，右，下）。

<强>用法：

onView(withId(id)).perform(clickDrawables());

方式：

public static ViewAction clickDrawables() { return new ViewAction() { @Override public Matcher<View> getConstraints()//must be a textview with drawables to do perform { return allOf(isAssignableFrom(TextView.class), new BoundedMatcher<View, TextView>(TextView.class) { @Override protected boolean matchesSafely(final TextView tv) { if(tv.requestFocusFromTouch())//get fpocus so drawables become visible for(Drawable d : tv.getCompoundDrawables())//if the textview has drawables then return a match if(d != null) return true; return false; } @Override public void describeTo(Description description) { description.appendText("has drawable"); } }); } @Override public String getDescription() { return "click drawables"; } @Override public void perform(final UiController uiController, final View view) { TextView tv = (TextView)view; if(tv != null && tv.requestFocusFromTouch())//get focus so drawables are visible { Drawable[] drawables = tv.getCompoundDrawables(); Rect tvLocation = new Rect(); tv.getHitRect(tvLocation); Point[] tvBounds = new Point[4];//find textview bound locations tvBounds[0] = new Point(tvLocation.left, tvLocation.centerY()); tvBounds[1] = new Point(tvLocation.centerX(), tvLocation.top); tvBounds[2] = new Point(tvLocation.right, tvLocation.centerY()); tvBounds[3] = new Point(tvLocation.centerX(), tvLocation.bottom); for(int location = 0; location < 4; location++) if(drawables[location] != null) { Rect bounds = drawables[location].getBounds(); tvBounds[location].offset(bounds.width() / 2, bounds.height() / 2);//get drawable click location for left, top, right, bottom if(tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, tvBounds[location].x, tvBounds[location].y, 0))) tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, tvBounds[location].x, tvBounds[location].y, 0)); } } } }; }

这是我为选择要点击的特定drawable所做的改进：

<强>用法：

onView(withId(id)).perform(new ClickDrawableAction(ClickDrawableAction.Right));

方式：

public static class ClickDrawableAction implements ViewAction { public static final int Left = 0; public static final int Top = 1; public static final int Right = 2; public static final int Bottom = 3; @Location private final int drawableLocation; public ClickDrawableAction(@Location int drawableLocation) { this.drawableLocation = drawableLocation; } @Override public Matcher<View> getConstraints() { return allOf(isAssignableFrom(TextView.class), new BoundedMatcher<View, TextView>(TextView.class) { @Override protected boolean matchesSafely(final TextView tv) { //get focus so drawables are visible and if the textview has a drawable in the position then return a match return tv.requestFocusFromTouch() && tv.getCompoundDrawables()[drawableLocation] != null; } @Override public void describeTo(Description description) { description.appendText("has drawable"); } }); } @Override public String getDescription() { return "click drawable "; } @Override public void perform(final UiController uiController, final View view) { TextView tv = (TextView)view;//we matched if(tv != null && tv.requestFocusFromTouch())//get focus so drawables are visible { //get the bounds of the drawable image Rect drawableBounds = tv.getCompoundDrawables()[drawableLocation].getBounds(); //calculate the drawable click location for left, top, right, bottom final Point[] clickPoint = new Point[4]; clickPoint[Left] = new Point(tv.getLeft() + (drawableBounds.width() / 2), (int)(tv.getPivotY() + (drawableBounds.height() / 2))); clickPoint[Top] = new Point((int)(tv.getPivotX() + (drawableBounds.width() / 2)), tv.getTop() + (drawableBounds.height() / 2)); clickPoint[Right] = new Point(tv.getRight() + (drawableBounds.width() / 2), (int)(tv.getPivotY() + (drawableBounds.height() / 2))); clickPoint[Bottom] = new Point((int)(tv.getPivotX() + (drawableBounds.width() / 2)), tv.getBottom() + (drawableBounds.height() / 2)); if(tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, clickPoint[drawableLocation].x, clickPoint[drawableLocation].y, 0))) tv.dispatchTouchEvent(MotionEvent.obtain(android.os.SystemClock.uptimeMillis(), android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, clickPoint[drawableLocation].x, clickPoint[drawableLocation].y, 0)); } } @IntDef({ Left, Top, Right, Bottom }) @Retention(RetentionPolicy.SOURCE) public @interface Location{} }

适用于截至 2021 年 1 月 7 日（欧洲格式）目前遇到此问题的人。我遇到了同样的问题并像这样解决了：

在你的 xml 中，也许你有这样的东西：

var
  Nums: array of Integer;

procedure TMyForm.FillListView;
var
  i, k, num: Integer;
begin
  k := StrToInt(Edit.Text);
  if k < 0 then k := 0;
  SetLength(Nums, k);
  for i := 0 to k-1 do
  begin
    num := ...;
    Nums[i] := num;
  end;
  ListView1.Items.Count := k;
  ListView1.Invalidate;
end;

procedure TMyForm.ListView1Data(Sender: TObject; Item: TListItem);
begin
  Item.Caption := IntToStr(Nums[Item.Index]);
  // set other properties as needed ...
end;

当你看到上面的xml代码时，我添加了<com.google.android.material.textfield.TextInputLayout android:id="@+id/edittext_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="@string/edittext_hint" app:endIconMode="clear_text" app:endIconCheckable="true" app:endIconTint="@color/colorSemiTranspBlack" app:endIconContentDescription="clear text"> <com.google.android.material.textfield.TextInputEditText android:id="@+id/eddittext" android:layout_width="match_parent" android:layout_height="wrap_content" /> </com.google.android.material.textfield.TextInputLayout>。从 xml 中抓取 app:endIconContentDescription="clear text" 并在您的 Instrumented 测试方法中添加 app:endIconContentDescription="clear text"，在您的测试类中，例如：

onView(withContentDescription("clear text")).perform(click());

忘记说这个@Test public void testEdittext(){ onView(withId(R.id.eddittext)).perform(typeText("Type something.")); onView(withContentDescription("clear text")).perform(click()); }是你必须先在edittext里面写点东西的那一行，这样结束图标（eddittext的右边drawable）才会出现然后点击。

Answer 4

我使用材料组件 TextInputLayout and TextInputEditText

解决了该问题

在您的xml中：

 <com.google.android.material.textfield.TextInputLayout
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
            android:id="@+id/til_location"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:endIconMode="custom"
            app:endIconDrawable="@drawable/ic_edit_location"
            app:endIconTint="@color/colorAccent"
            app:hintEnabled="false"
            app:endIconContentDescription="open map icon">

            <com.google.android.material.textfield.TextInputEditText
                android:id="@+id/et_address"
                android:textColor="@color/colorAccent"
                android:layout_height="wrap_content"
                android:layout_width="match_parent"
                tools:text="3 streenasdasdasd"/>

        </com.google.android.material.textfield.TextInputLayout>

这里的技巧是设置app:endIconMode="custom"，然后根据需要添加可绘制对象。

在Java类中：

您可以使用setEndIconOnClickListener并执行以下操作：

tilLocation.setEndIconOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //do click
        }
    });
