AlertDialog的问题检索组件-android
|
我正在尝试使用视图构建一个Alertdialog，并访问TextView来设置其文本值。这是代码：
private void ShowLogDialog() {
AlertDialog ad = new AlertDialog.Builder(this).create();
ad.setIcon(R.drawable.icon);
ad.setTitle(\"Ultimate Logs\");
ad.setView(LayoutInflater.from(this).inflate(R.layout.log_layout, null));
TextView text = (TextView)ad.findViewById(R.id.logTextView_log); // RETURNS NULL
//Log.i(TAG, \"Into ShowLogDialog : GoT TextView = \" + text);
//String logsText = \"\";
//text.setText(logsText);
ad.setButton(\"Ok\", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
ad.show();
}
<LinearLayout android:id=\"@+id/linearLayout1\" android:layout_width=\"match_parent\" android:layout_height=\"match_parent\"
android:orientation=\"vertical\" android:scrollbars=\"vertical\" android:scrollbarAlwaysDrawVerticalTrack=\"true\" xmlns:android=\"http://schemas.android.com/apk/res/android\">
<TextView android:layout_height=\"wrap_content\" android:text=\"TextView\" android:id=\"@+id/**logTextView_log**\" android:layout_width=\"wrap_content\"></TextView>
</LinearLayout>

AlertDialog.Builder builder= new AlertDialog.Builder(this); LayoutInflater inflater= getLayoutInflater(); final View myView= inflater.inflate(R.layout.alert_dialog_text_entry, null); builder.setTitle(\"About\"); builder.setMessage(\"Test\"); builder.setView(myView); AlertDialog alert= builder.create(); TextView stateful= (TextView)myView.findViewById(R.id.TextView01); stateful.setText(\"More Testing\"); Log.d(Utilities.TAG,stateful.toString()); alert.show();逆捐凶撤小

返回到变量？ （以下代码未经测试）ad.setTitle(\"Ultimate Logs\"); View inflatedView = LayoutInflater.from(this).inflate(R.layout.log_layout, null); TextView text = (TextView)inflatedView.findViewById(R.id.logTextView_log); // RETURNS NULL Log.i(TAG, \"Into ShowLogDialog : GoT TextView = \" + text); String logsText = \"\"; text.setText(logsText); ad.setView(inflatedView ); ad.setButton(\"Ok\", new DialogInterface.OnClickListener() {
