使用搜索栏更改AlertDialog消息

seekbar android-alertdialog android

Alxlly · 技术社区 · 10 年前

我有一个警报对话框,但我想根据搜索栏中的值更改中的消息

吐司做得很好,但我不知道如何在警报对话框消息上实现这是我目前的代码

public void requestCheckButton(View view){

    final AlertDialog.Builder popDialog = new AlertDialog.Builder(this);
    final SeekBar seek = new SeekBar(this);
    seek.setMax(11); // Para tener incrementos de 5 min

    popDialog.setTitle("Â¿En cuÃ¡nto tiempo puedes llegar?");
    popDialog.setMessage("15 min");
    popDialog.setView(seek);
    popDialog.setPositiveButton("Mandar", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "Presionaste Mandar", Toast.LENGTH_SHORT).show();
        }
    });

    seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        int progress = 0;

        public void onProgressChanged(SeekBar seekBar, int progressV, boolean fromUser) {
            progress = progressV;
        }


        public void onStartTrackingTouch(SeekBar arg0) {

        }


        public void onStopTrackingTouch(SeekBar seekBar) {
            //Por cada incremento se suman 5 min
            Toast.makeText(getApplicationContext(), (progress)*5 +"min", Toast.LENGTH_SHORT).show();
        }
    });
    popDialog.show();
}

删除popDialog.show();
添加之前 seek.setOnSeekBarChangeListener

最终AlertDialog对话框=popDialog.create();
调用dialog.setMessage()代替toast;
添加对话框。最后显示()

如此更正的代码:

    final AlertDialog.Builder popDialog = new AlertDialog.Builder(this);
    final SeekBar seek = new SeekBar(this);
    seek.setMax(11); // Para tener incrementos de 5 min

    popDialog.setTitle("Â¿En cuÃ¡nto tiempo puedes llegar?");
    popDialog.setMessage("15 min");
    popDialog.setView(seek);
    popDialog.setPositiveButton("Mandar", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "Presionaste Mandar", Toast.LENGTH_SHORT).show();
        }
    });
    final AlertDialog dialog = popDialog.create();
    seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        int progress = 0;

        public void onProgressChanged(SeekBar seekBar, int progressV, boolean fromUser) {
            progress = progressV;
        }


        public void onStartTrackingTouch(SeekBar arg0) {

        }


        public void onStopTrackingTouch(SeekBar seekBar) {
            //Por cada incremento se suman 5 min
            dialog.setMessage((progress)*5 +"min");
        }
    });
    dialog.show();
}

您可以使用同时包含文本视图和搜索栏的视图:

对话框.xml

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

 <TextView
        android:id="@+id/text_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <SeekBar
        android:id="@+id/seekbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

而不是 setView(seek) :

View view = View.inflate(context, R.layout.dialog, null);
final SeekBar seekBar = (Seekbar) view.findViewById(R.id.seekbar);
final TextView textView = (TextView) view.findViewById(R.id.text_view);
popDialog.setView(view);

在听众中:

public void onStopTrackingTouch(SeekBar seekBar) {
            textView.setText(seekBar.getProgress() + "");
        }
