Question

我需要帮助实现代码添加一个否定或肯定的按钮来关闭我的警报对话（任何帮助将不胜感激）。我认为代码中的一些标点符号也需要改变，所以任何帮助都会很棒：）

package kevin.erica.box;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.content.res.Resources;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
import android.widget.TextView;
import java.util.Random;

public class TheKevinAndEricaBoxActivity extends Activity {
/** Called when the activity is first created. */
private String[] myString;
private String list;
private String[] myString2;
private String list2;
private static final Random rgenerator = new Random();
private static final Random rgenerator2 = new Random();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Resources res = getResources();

    myString = res.getStringArray(R.array.myArray);

    list = myString[rgenerator.nextInt(myString.length)];

    myString2 = res.getStringArray(R.array.myArray2);

    list2 = myString2[rgenerator.nextInt(myString2.length)];

    ImageButton ib = (ImageButton) findViewById(R.id.imagebutton1);
    ib.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View erica) {
            AlertDialog.Builder b = new AlertDialog.Builder(
                    TheKevinAndEricaBoxActivity.this);
                  b.setMessage(myString[rgenerator.nextInt(myString.length)]);
            b.setTitle(R.string.title1); 
Dialog d = b.create();
            d.show();

        }
    });
}
}

Answer 1

您可以在app ::::

中使用以下代码

AlertDialog.Builder b = new AlertDialog.Builder(TheKevinAndEricaBoxActivity.this);
b.setMessage(myString[rgenerator.nextInt(myString.length)]);
b.setTitle(R.string.title1); 
b.setPositiveButton("Button Text", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which){
    //stuff you want the button to do
}
});
b.setNegativeButton("Button Text", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which){
    //stuff you want the button to do
}
});

Here is a guide.

注意函数“set_ _ _Button”。

Answer 3

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                context);

            // set title
            alertDialogBuilder.setTitle("Your Title");

            // set dialog message
            alertDialogBuilder
                .setMessage("Click yes to exit!")
                .setCancelable(false)
                .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked, close
                        // current activity
                        MainActivity.this.finish();
                    }
                  })
                .setNegativeButton("No",new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int id) {
                        // if this button is clicked, just close
                        // the dialog box and do nothing
                        dialog.cancel();
                    }
                });

                // create alert dialog
                AlertDialog alertDialog = alertDialogBuilder.create();

                // show it
                alertDialog.show();

Answer 4

b.setNegativeButton("Button Text", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which){
    //stuff you want the button to do
});

Answer 5

您需要制作自定义对话框。见样本：

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);

这是完整的样本：
