最终会调用UiObject.getContentDescription()方法获得控件当描述信息
package io.appium.android.bootstrap.handler;
import com.android.uiautomator.core.UiObjectNotFoundException;
import io.appium.android.bootstrap.*;
import io.appium.android.bootstrap.exceptions.NoAttributeFoundException;
import org.json.JSONException;

*
* @return {@link AndroidCommandResult}
*
* @throws JSONException
*
* @see io.appium.android.bootstrap.CommandHandler#execute(io.appium.android.
* bootstrap.AndroidCommand)
*/
@Override
public AndroidCommandResult execute(final AndroidCommand command)
throws JSONException {
if (command.isElementCommand()) {
// only makes sense on an element
final Hashtable<String, Object> params = command.params();
try {
final AndroidElement el = command.getElement();
final String attr = params.get("attribute").toString();
if (attr.equals("name") || attr.equals("text")
|| attr.equals("className")) {
return getSuccessResult(el.getStringAttribute(attr));
} else {
return getSuccessResult(String.valueOf(el.getBoolAttribute(attr)));
}
} catch (final NoAttributeFoundException e) {
return new AndroidCommandResult(WDStatus.NO_SUCH_ELEMENT,
e.getMessage());
} catch (final UiObjectNotFoundException e) {
return new AndroidCommandResult(WDStatus.NO_SUCH_ELEMENT,
e.getMessage());
} catch (final Exception e) { // el is null
return new AndroidCommandResult(WDStatus.NO_SUCH_ELEMENT,
e.getMessage());
}
} else {
return getErrorResult("Unable to get attribute without an element.");
}
}
}
该事件是为获取控件相关信息设置的，来看看可以获取哪些信息，其实就是uiautomatorviewer里的信息。
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;
}
文本值：content－desc、text、className.
public boolean getBoolAttribute(final String attr)
throws UiObjectNotFoundException, NoAttributeFoundException {
boolean res;
if (attr.equals("enabled")) {
res = el.isEnabled();
} else if (attr.equals("checkable")) {
res = el.isCheckable();
} else if (attr.equals("checked")) {
res = el.isChecked();
} else if (attr.equals("clickable")) {
res = el.isClickable();
} else if (attr.equals("focusable")) {
res = el.isFocusable();
} else if (attr.equals("focused")) {
res = el.isFocused();
} else if (attr.equals("longClickable")) {
res = el.isLongClickable();
} else if (attr.equals("scrollable")) {
res = el.isScrollable();
} else if (attr.equals("selected")) {
res = el.isSelected();
} else if (attr.equals("displayed")) {
res = el.exists();
} else {
throw new NoAttributeFoundException(attr);
}
return res;
}
boolean类型的值：如上等等。
package io.appium.android.bootstrap.handler;
import com.android.uiautomator.core.UiDevice;
import io.appium.android.bootstrap.AndroidCommand;
import io.appium.android.bootstrap.AndroidCommandResult;
import io.appium.android.bootstrap.CommandHandler;
import org.json.JSONException;
import org.json.JSONObject;
/**
* This handler is used to get the size of the screen.
*
*/
public class GetDeviceSize extends CommandHandler {
/*
* @param command The {@link AndroidCommand} used for this handler.
*
* @return {@link AndroidCommandResult}
*
* @throws JSONException
*
* @see io.appium.android.bootstrap.CommandHandler#execute(io.appium.android.
* bootstrap.AndroidCommand)
*/
@Override
public AndroidCommandResult execute(final AndroidCommand command) {
if (!command.isElementCommand()) {
// only makes sense on a device
final UiDevice d = UiDevice.getInstance();
final JSONObject res = new JSONObject();
try {
res.put("height", d.getDisplayHeight());
res.put("width", d.getDisplayWidth());
} catch (final JSONException e) {
getErrorResult("Error serializing height/width data into JSON");
}
return getSuccessResult(res);
} else {
return getErrorResult("Unable to get device size on an element.");
}
}
}
获取屏幕的长和宽，调用的是UiDevice的方法：getDisplayHeight()和getDisplayWidth()
package io.appium.android.bootstrap.handler;
import android.graphics.Rect;
import com.android.uiautomator.core.UiObjectNotFoundException;
import io.appium.android.bootstrap.*;
import org.json.JSONException;
import org.json.JSONObject;
/**
* This handler is used to get the size of elements that support it.
*
*/
public class GetSize extends CommandHandler {
/*
* @param command The {@link AndroidCommand} used for this handler.
*
* @return {@link AndroidCommandResult}
*
* @throws JSONException
*
* @see io.appium.android.bootstrap.CommandHandler#execute(io.appium.android.
* bootstrap.AndroidCommand)
*/
@Override
public AndroidCommandResult execute(final AndroidCommand command)
throws JSONException {
if (command.isElementCommand()) {
// Only makes sense on an element
final JSONObject res = new JSONObject();
try {
final AndroidElement el = command.getElement();
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 getErrorResult("Unknown error");
}
return getSuccessResult(res);
} else {
return getErrorResult("Unable to get text without an element.");
}
}
}
获取控件的宽和高，调用的是UiObject的getBounds()。得到一个矩形，然后获得其宽和高。
package io.appium.android.bootstrap.handler;
import android.graphics.Rect;
import io.appium.android.bootstrap.*;
import org.json.JSONException;
import org.json.JSONObject;
/**
* This handler is used to get the text of elements that support it.
*
*/
public class GetLocation extends CommandHandler {
/*
* @param command The {@link AndroidCommand} used for this handler.
*
* @return {@link AndroidCommandResult}
*
* @throws JSONException
*
* @see io.appium.android.bootstrap.CommandHandler#execute(io.appium.android.
* bootstrap.AndroidCommand)
*/
@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());
}
}
}
获取控件的起始点坐标。调用的也是getBounds,然后得到其起始点的x,y 坐标
package io.appium.android.bootstrap.handler;
import android.os.Environment;
import io.appium.android.bootstrap.AndroidCommand;
import io.appium.android.bootstrap.AndroidCommandResult;
import io.appium.android.bootstrap.CommandHandler;
/**
* This handler is used to get the data dir.
*
*/
public class GetDataDir extends CommandHandler {
/*
* @param command The {@link AndroidCommand} used for this handler.
*
* @return {@link AndroidCommandResult}
*
* @throws JSONException
*
* @see io.appium.android.bootstrap.CommandHandler#execute(io.appium.android.
* bootstrap.AndroidCommand)
*/
@Override
public AndroidCommandResult execute(final AndroidCommand command) {
return getSuccessResult(Environment.getDataDirectory());
}
}
获取data的根目录。调用的是android的api：Environment.getDataDirectory()
