        </LinearLayout>

    </ScrollView>

这是我的完整代码，因为你请求了@mobie .. Symptoms.java和question.xml ..不管其他代码。只是在我问的警告对话框上。

Answer 1

为对话框创建如下所示的布局：dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<ImageView
    android:id="@+id/image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginRight="5dp" />

<TextView
    android:id="@+id/text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#FFF" 
    android:layout_toRightOf="@+id/image"/>

<Button
    android:id="@+id/dialogButtonOK"
    android:layout_width="100px"
    android:layout_height="wrap_content"
    android:text=" Ok "
    android:layout_marginTop="5dp"
    android:layout_marginRight="5dp"
    android:layout_below="@+id/image"
    />

</RelativeLayout>

然后，您要放置警报的位置，请执行以下操作

 final Dialog dialog = new Dialog(context);
        dialog.setContentView(R.layout.dialog);
        dialog.setTitle("Your Title");

        TextView text = (TextView) dialog.findViewById(R.id.text);
        text.setText("Text");
        ImageView image = (ImageView) dialog.findViewById(R.id.image);
        image.setImageResource(R.drawable.ic_launcher);

        Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
        dialogButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        dialog.show();
