GetName

package io.appium.android.bootstrap.handler;

import com.android.uiautomator.core.UiObjectNotFoundException;

import io.appium.android.bootstrap.*;

import org.json.JSONException;

/**

* This handler is used to get the text of elements that support it.

*/

public class GetName 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 name without an element.");

}

try {

final AndroidElement el = command.getElement();

return getSuccessResult(el.getContentDesc());

} catch (final UiObjectNotFoundException e) {

return new AndroidCommandResult(WDStatus.NO_SUCH_ELEMENT, e.getMessage());

} catch (final Exception e) { // handle NullPointerException

return getErrorResult("Unknown error");

}

}

}

最终会调用UiObject.getContentDescription()方法获得控件当描述信息

GetAttribute

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;

import java.util.Hashtable;

/**

* This handler is used to get an attribute of an element.

*

*/

public class GetAttribute 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 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。

GetDeviceSize

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()

GetSize

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。

GetLocation

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

GetDataDir

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()
