Android无线测试之—UiAutomator UiObject API介绍七

判断对象是否存在

1、判断对象是否存在相关API

返回值	API	描述
boolean	waitForExists(long timeout)	等待对象出现
boolean	waitUntilGone(long timeout)	等待对象消失
boolean	exists()	检查对象是否存在

2、API应用举例

package com.test.uiobject;

import java.io.File;

import android.graphics.Rect;
import android.view.KeyEvent;

import com.android.uiautomator.core.UiDevice;
import com.android.uiautomator.core.UiObject;

import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

        testName="testExists";
        androidId="1";
        new UiAutomatorHelper(jarName,testClass,testName,androidId);

    }
    
    public void testExists() throws UiObjectNotFoundException{
        UiDevice.getInstance().pressHome();

        if(text.exists()){

        }
        
        UiObject create=new UiObject(new UiSelector().resourceId("com.android.mms:id/action_compose_new"));

            create.click();
            UiObject to=new UiObject(new UiSelector().resourceId("com.android.mms:id/recipients_editor"));
            to.click();
            UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_1);
            UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_0);
            UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_0);

            UiObject typeMessage=new UiObject(new UiSelector().resourceId("com.android.mms:id/embedded_text_editor"));
            typeMessage.setText("hello, my name is fsw!");
            UiObject button=new UiObject(new UiSelector().resourceId("com.android.mms:id/send_button_sms"));
            button.click();
            sleep(2000);
        }
    }
