Custom dialog in android not working

Question

I have to implement a custom dialog in my application, But my codes seems not working. Please help me.

Thanks in advance.

This is my code:

Context mContext = getApplicationContext();
Dialog dialog = new Dialog(mContext);

dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("Custom Dialog");

TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.android);

And this is my layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/layout_root"
              android:orientation="horizontal"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:padding="10dp"
              >
    <ImageView android:id="@+id/image"
               android:layout_width="wrap_content"
               android:layout_height="fill_parent"
               android:layout_marginRight="10dp"
               />
    <TextView android:id="@+id/text"
              android:layout_width="wrap_content"
              android:layout_height="fill_parent"
              android:textColor="#FFF"
              />
</LinearLayout>

Answer 1

您可以尝试使用dialog.Show()

Answer 2

Instead of using setContentView() , get the LayoutInflater, the=n do whatever you want to do with the layout, then add it to the dialog using setView() method.

Because in case of AlertDialog, setContentView will not work.

Answer 3

I would insist not to use getApplicationContext() to create the Dialog instance rather use Activitys instance to create it.

Dialog dialog = new Dialog(Activity_Name.this);

Also make sure you are calling dialog.show(); after creating your Dialog.

Answer 4

Dialog listDialog = new Dialog(this);
listDialog.setTitle(getString(R.string.picktemplate));
LayoutInflater li = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = li.inflate(R.layout.custom_dialog, null, false);
listDialog.setContentView(view);
listDialog.setCancelable(true);

Button list1 = (Button) listDialog.findViewById(R.id.btnList);
listDialog.show();
