一、设计布局
<Button
ohos:height="match_content"
ohos:width="match_parent"
ohos:id="$+id:GetAppInfo"
ohos:padding="5fp"
ohos:top_margin="10fp"
ohos:left_margin="20fp"
ohos:right_margin="20fp"
ohos:bottom_margin="10fp"
ohos:text_size="22fp"
ohos:text_color="#fff"
ohos:background_element="$graphic:background_button"
ohos:text="获取应用程序信息"></Button>
<Text
ohos:height="match_content"
ohos:width="match_parent"
ohos:id="$+id:ShowAPPInfo"
ohos:left_padding="20fp"
ohos:right_padding="20fp"
ohos:top_padding="0fp"
ohos:text_size="14fp"
ohos:text_color="#fff"
ohos:multiple_lines="true"
ohos:text=""></Text>
二、打开MainAbilitySlice.JAVA文件录入以下关键代码
private static final HiLogLabel hiLogLabel = new HiLogLabel(HiLog.LOG_APP, 0x00888, "BingJunNetWorkLog");
private Text ShowAPPInfo;
@Override
public void onStart(Intent intent) {
super.onStart(intent);
super.setUIContent(ResourceTable.Layout_ability_main);
Button GetAPPInfo=(Button) findComponentById(ResourceTable.Id_GetAPPInfo);
GetAPPInfo.setClickedListener(clickedListener);
ShowAPPInfo=(Text) findComponentById(ResourceTable.Id_ShowAPPInfo);
}
public Component.ClickedListener clickedListener= component -> {
switch (component.getId()){
case ResourceTable.Id_GetAPPInfo:
ShowAPPInfo.setText("");
this.UpdateAPPInfo();
break;
default:
break;
}
};
public void UpdateAPPInfo(){
TaskDispatcher taskDispatcher=this.getUITaskDispatcher();
