Dialog 不显示

最近遇到一个dialog 不显示问题；

下载代码用了retrofit 框架

mActivity.runOnUiThread(new Runnable() {
public void run() {
HttpUtil httpUtil = new HttpUtil();
Map<String, String> map = new HashMap<String, String>();
map.put("URL", "16891/9EADA8BA0CE54C4293C47ABA01AD202C.apk?fsname=com.tencent.mm_6.3.25_861.apk&csr=4d5s");
map.put("PACKAGENAME", getListenPackageName());
httpUtil.downapkFromServer(mActivity,map);
httpUtil.setListener(new ResponseListener() {
@Override
public void result(Object obj) {
if(obj instanceof String){
if(obj.equals("OK")){
SPrefHookUtil.putSettingBoolean(mActivity, SPrefHookUtil.KEY_SETTING_APK_INSTALL, true);
showDialog();
CmdUtil.installApk(mActivity, path);
}
}
}
});
}
});

结果 showDialog 也执行了，判断 dialog.isShowing() 返回结果为true；但是界面上就是没有弹出框

原因：CmdUtil.installApk(mActivity, path); shell命令为耗时操作，需要放到线程中

修改

mActivity.runOnUiThread(new Runnable() {
public void run() {
HttpUtil httpUtil = new HttpUtil();
Map<String, String> map = new HashMap<String, String>();
map.put("URL", "16891/9EADA8BA0CE54C4293C47ABA01AD202C.apk?fsname=com.tencent.mm_6.3.25_861.apk&csr=4d5s");
map.put("PACKAGENAME", getListenPackageName());
httpUtil.downapkFromServer(mActivity,map);
httpUtil.setListener(new ResponseListener() {
@Override
public void result(Object obj) {
if(obj instanceof String){
if(obj.equals("OK")){
SPrefHookUtil.putSettingBoolean(mActivity, SPrefHookUtil.KEY_SETTING_APK_INSTALL, true);
showDialog();
new Thread(new Runnable() {
@Override
public void run() {
CmdUtil.installApk(mActivity, path);
}
}).start();
}
}
}
});
}
});

同时 dialog 要在主线程显示
