多按钮的点击事件其实与只有一个是类似的，只不过要在调用 onClick（）时进行判断，判断获取到的component是谁即可。
package com.example.yeman.slice; import com.example.yeman.ResourceTable; import ohos.aafwk.ability.AbilitySlice; import ohos.aafwk.content.Intent; import ohos.agp.components.Button; import ohos.agp.components.Component; import ohos.agp.components.Text; public class MainAbilitySlice extends AbilitySlice implements Component.ClickedListener { Text text1; Button login; Button register; @Override public void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_main); //1.找到文本框组件，按钮组件 text1 = (Text) findComponentById(ResourceTable.Id_text1); login = (Button) findComponentById(ResourceTable.Id_login); register = (Button) findComponentById(ResourceTable.Id_register); login.setClickedListener(this); register.setClickedListener(this); } @Override public void onActive() { super.onActive(); } @Override public void onForeground(Intent intent) { super.onForeground(intent); } @Override public void onClick(Component component) { //先做一个判断 //判断当前点击的是登录按钮还是注册按钮 //component表示当前点击的组件 if(component == login){ //表示现在点击的是登录按钮 text1.setText("点击了登录按钮"); }else if(component == register){ //表示现在点击的是注册按钮 text1.setText("点击了注册按钮"); } } }
