我想显示 AsyncTask 中其他类中的 AlertDialog。 示例>
public class WardListAsyncTask extends AsyncTask<HashMap<String, String>, String, Object> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Object doInBackground(HashMap<String, String>... params) {
...
}
@Override
protected void onPostExecute(Object result) {
ConfirmAlertDialog(ez_WardList.this,"HI?");
//this method is in another Class & I want to use this method another Asynctask also..
}
ConfirmAlertDialog 是...
Context g_ctx;
String g_content;
public void ez_ConfirmAlertDialog(Context ctx, String content) {
this.g_ctx=ctx;
this.g_content=content;
runOnUiThread(new Runnable() {
@Override
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(g_ctx, AlertDialog.THEME_HOLO_LIGHT);
builder.setMessage(g_content).setPositiveButton(getString(R.string.kor_confirm),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(displayWidth / 2, LayoutParams.WRAP_CONTENT);
alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.rgb(10, 174, 239));
}
});
}
我认为 g_ctx.class.runonuiThread ...但我无法调用 runonuithread...
如何解决？
最佳答案
Activity 类中存在 runOnUiThread 方法。因此应该将 Activity 传递到您的类(class)中。 示例:
public class MyClass{
public void ez_ConfirmAlertDialog(Activity activity, String content) {
this.g_ctx=ctx;
this.g_content=content;
if(activity == null){
return;
}
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(g_ctx, AlertDialog.THEME_HOLO_LIGHT);
builder.setMessage(g_content).setPositiveButton(getString(R.string.kor_confirm),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(displayWidth / 2, LayoutParams.WRAP_CONTENT);
alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.rgb(10, 174, 239));
}
});
}
}
关于android - 有没有一种方法可以在AsyncTask中显示AlertDialog？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39161791/
