このイベントは、コントロールに関する情報を取得するために設定されています.どの情報を取得できるかを見てみましょう.実はuiautomatorviewerの情報です.

public String getStringAttribute(final String attr)
      throws UiObjectNotFoundException, NoAttributeFoundException {
    String res;
    if (attr.equals("name")) {
      res = getContentDesc();
      if (res.equals("")) {
        res = getText();
      }
    } else if (attr.equals("text")) {
      res = getText();
    } else if (attr.equals("className")) {
      res = getClassName();
    } else {
      throw new NoAttributeFoundException(attr);
    }
    return res;
  }

テキスト値:content-desc、text、className.

public boolean getBoolAttribute(final String attr)
      throws UiObjectNotFoundException, NoAttributeFoundException {
    boolean res;
    if (attr.equals("enabled")) {
      res = el.isEnabled();

      res = el.exists();
    } else {
      throw new NoAttributeFoundException(attr);
    }
    return res;

booleanタイプの値:上記など.

GetDeviceSize

      }
      return getSuccessResult(res);
    } else {
      return getErrorResult("Unable to get device size on an element.");
    }
  }
}

画面の長さと幅を取得し、UiDeviceのメソッドを呼び出します:getDisplayHeight()とgetDisplayWidth()

GetSize

import android.graphics.Rect;
import com.android.uiautomator.core.UiObjectNotFoundException;
import io.appium.android.bootstrap.*;

        final Rect rect = el.getBounds();
        res.put("width", rect.width());
        res.put("height", rect.height());
      } catch (final UiObjectNotFoundException e) {
        return new AndroidCommandResult(WDStatus.NO_SUCH_ELEMENT,
            e.getMessage());
      } catch (final Exception e) { // handle NullPointerException

      }
      return getSuccessResult(res);
    } else {
      return getErrorResult("Unable to get text without an element.");
    }
  }
}

コントロールの幅と高さを取得し、UiobjectのgetBounds()を呼び出します.長方形が得られ、その後、その幅と高さが得られる.

GetLocation

package io.appium.android.bootstrap.handler;

import android.graphics.Rect;
import io.appium.android.bootstrap.*;
import org.json.JSONException;
import org.json.JSONObject;

/**

  @Override
  public AndroidCommandResult execute(final AndroidCommand command)
      throws JSONException {
    if (!command.isElementCommand()) {
      return getErrorResult("Unable to get location without an element.");
    }

    try {
      final JSONObject res = new JSONObject();
      final AndroidElement el = command.getElement();
      final Rect bounds = el.getBounds();
      res.put("x", bounds.left);
      res.put("y", bounds.top);
      return getSuccessResult(res);
    } catch (final Exception e) {
      return new AndroidCommandResult(WDStatus.NO_SUCH_ELEMENT, e.getMessage());
    }
  }
}

コントロールの開始点座標を取得します.呼び出されたのもgetBoundsで、その開始点のx,y座標が得られます.
