如何设置警报对话框警报文本大小 [英] How to set Alert text size in alert dialog

问题描述

默认警报消息是太大了，几乎没有屏幕的特定设备，我想将它设置为自定义DP

The alert message by default is too big for specific devices with little screens and I want to set it to a custom dp

我的提醒是这样

OnClickListener addNewItemListener = new OnClickListener() {
                public void onClick(View v) {
                    AlertDialog.Builder alert = new AlertDialog.Builder(
                            MyActivity.this);

                    LinearLayout myLayout= new LinearLayout(MyActivity.this);
                    myLayout.setOrientation(LinearLayout.VERTICAL);

                    alert.setTitle(R.string.add_title);
                    alert.setMessage(R.string.add_message);

                    final TextView t1 = new TextView(MyActivity.this);
                    t1.setText("Name");
                    final EditText input1 = new EditText(MyActivity.this);
                    myLayout.addView(t1);
                    myLayout.addView(input1);
                    alert.setView(myLayout);
                    alert.setPositiveButton(R.string.cancel,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int whichButton) {
                                }
                            });
                    alert.setNegativeButton(R.string.ok,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int whichButton) {
                                    try {
                                        ....
                                    } catch (RuntimeException e) {
                                        Alerts.DatiErrati(MyActivity.this);
                                    }

                                }
                            });
                    alert.show();
                }
            };

编辑2：

这是你可以用

AlertDialog.Builder builder = new Builder(this);
builder.setMessage("Record and Images will be deleted?")
        .setTitle("MyTitle")
        .setCancelable(true)
        .setPositiveButton("Yes",
                        new DialogInterface.OnClickListener()
                        {

                            public void onClick(DialogInterface dialog,
                                    int id)
                            {

                                dialog.cancel();
                                finish();
                            }
                        })
                .setNegativeButton("No",
                        new DialogInterface.OnClickListener()
                        {

                            public void onClick(DialogInterface dialog,
                                    int id)
                            {
                                dialog.cancel();
                            }
                        });
        AlertDialog dialog = builder.create();
        dialog.show();
        TextView textView = (TextView) dialog.findViewById(android.R.id.message);
        textView.setTextSize(40);

您可以使用以下得到较大的纯文本

You can use the following to get bigger text only

  alert.setMessage(Html.fromHtml("<Big>"+getString(R.string.add_message)+"</Big>"));

注意：：您可以使用更多的大的更多更大的文本

Note: you can use more big's for more bigger text
