builder.setView(edit); builder.setPositiveButton("确认", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { try { lat = Double.parseDouble(edit.getText().toString()); // 存储数据 SharedPreferences.Editor editor = getSharedPreferences("data", MODE_PRIVATE).edit(); editor.putString("lat", Double.toString(lat)); editor.apply(); } catch (NumberFormatException e) { MyToast.makeText(XbyActivity.this, "输入数据有误", Toast.LENGTH_SHORT, true).show(); // 返回上个页面 Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); } } });可以用log打印的值有啥

可以用log打印出以下值：

1. `edit.getText().toString()`：获取EditText中输入的文本内容。
2. `lat`：将EditText中输入的文本内容转换为double类型后的值。
3. 存储在SharedPreferences中的`lat`值，即`Double.toString(lat)`。

例如：

Log.d("TAG", "EditText value: " + edit.getText().toString());
Log.d("TAG", "lat: " + lat);
Log.d("TAG", "Stored lat value: " + Double.toString(lat));

以下代码,如何让弹窗必须选择后才能继续向下运行,要等待弹窗确认final int[] ide = {0}; unit_kind = "科室"; unit_xingzhi = ""; String[] keys = kezhang_names.keySet().toArray(new String[0]); View view = LayoutInflater.from(LuzhiAdmin_Xiangmu_Xiao0.this).inflate(R.layout.tanchuang, null); AlertDialog.Builder builder = new AlertDialog.Builder(LuzhiAdmin_Xiangmu_Xiao0.this); builder.setView(view); builder.setTitle("确定人员:"); builder.setSingleChoiceItems(keys, 0, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { ide[0] = which; return; } }).setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { id_perx = "#"+kezhang_names.get(keys[ide[0]])+"#"; } }); AlertDialog dialog = builder.create(); Window window = dialog.getWindow(); if (window != null) { WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams(); layoutParams.width = 600; layoutParams.height = 800; window.setAttributes(layoutParams); } dialog.setOnDismissListener(new DialogInterface.OnDismissListener() { @Override public void onDismiss(DialogInterface dialogInterface) { //等待确认执行 } }); dialog.show();

你可以在弹窗的"确定"按钮的点击事件中，将"ide[0]"的值更新为当前选中项的索引。然后在弹窗的"onDismiss"方法中，判断"ide[0]"的值是否发生了变化，如果没有变化，说明用户没有做出选择，可以弹出提示框提示用户进行选择，否则继续向下执行。代码如下所示：

final int[] ide = {-1}; // 初始化为-1，表示用户还没有做出选择
unit_kind = "科室";
unit_xingzhi = "";
String[] keys = kezhang_names.keySet().toArray(new String[0]);
View view = LayoutInflater.from(LuzhiAdmin_Xiangmu_Xiao0.this).inflate(R.layout.tanchuang, null);
AlertDialog.Builder builder = new AlertDialog.Builder(LuzhiAdmin_Xiangmu_Xiao0.this);
builder.setView(view);
builder.setTitle("确定人员:");
builder.setSingleChoiceItems(keys, 0, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        ide[0] = which;
        return;
    }
}).setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        if (ide[0] == -1) {
            // 如果用户没有做出选择，弹出提示框
            Toast.makeText(LuzhiAdmin_Xiangmu_Xiao0.this, "请先选择人员", Toast.LENGTH_SHORT).show();
            return;
        }
        id_perx = "#" + kezhang_names.get(keys[ide[0]]) + "#";
    }
});
AlertDialog dialog = builder.create();
Window window = dialog.getWindow();
if (window != null) {
    WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
    layoutParams.width = 600;
    layoutParams.height = 800;
    window.setAttributes(layoutParams);
}
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
    @Override
    public void onDismiss(DialogInterface dialogInterface) {
        if (ide[0] == -1) {
            // 如果用户没有做出选择，弹出提示框
            Toast.makeText(LuzhiAdmin_Xiangmu_Xiao0.this, "请先选择人员", Toast.LENGTH_SHORT).show();
            return;
        }
        // 继续向下执行
    }
});
dialog.show();

这样，弹窗就会等待用户做出选择后才能继续向下执行。如果用户没有做出选择，会弹出提示框提醒用户。

您好，以下是将发送信息从主线程中改为子线程的代码：

sendMessageButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        showSendMessageDialog();
    }
});

private void showSendMessageDialog() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    LayoutInflater inflater = getLayoutInflater();
    View view = inflater.inflate(R.layout.dialog_send_message, null);
    final EditText messageEditText = view.findViewById(R.id.messageEditText);
    builder.setView(view)
            .setTitle("发送消息")
            .setPositiveButton("发送", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    String message = messageEditText.getText().toString();
                    if (out != null) {
                        new Thread(new Runnable() {
                            @Override
                            public void run() {
                                out.println(message);
                            }
                        }).start();
                    }
                }
            })
            .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                }
            })
            .create()
            .show();
}

在这个改动中，我们将发送消息的操作放到了一个新的子线程中，防止阻塞主线程。
