Question

我正在尝试创建自定义警报对话框，其中两个字段是编辑文本，另一个是微调器。问题是我只能看到微调器，我无法看到编辑文本。编辑文本可用，但微调器隐藏了编辑文本的内容。所以我的问题是我如何设置编辑文本和Spinner的位置。

以下是我的代码。

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
            RecordAudio.this);
    alertDialog.setTitle("Would you Like to save your Recording");
    alertDialog.setMessage("Enter Audio Name");
    alertDialog.setIcon(R.drawable.save_icon);

    final EditText editTextAudioName = new EditText(RecordAudio.this);
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);
    editTextAudioName.setLayoutParams(lp);
    alertDialog.setView(editTextAudioName);

    final Spinner spinnerListData = new Spinner(RecordAudio.this);
    RelativeLayout.LayoutParams lpSpinner = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);
    spinnerListData.setLayoutParams(lpSpinner);
    alertDialog.setView(spinnerListData);

    dataManipulatorClass = new DataManipulatorClass(this);
    names2 = dataManipulatorClass.selectAll();

    stg1 = new String[names2.size()];
    int x = 0;
    String stg;

    for (String[] name : names2) {
        stg = "Class Name : " + name[1];
        stg1[x] = stg;
        x++;
    }

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(
            RecordAudio.this, android.R.layout.simple_spinner_item, stg1);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinnerListData.setAdapter(adapter);
    spinnerListData.setWillNotDraw(false);

    spinnerListData.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View v,
                int position, long id) {
            Toast.makeText(getApplicationContext(),
                    "Spinner Item selected", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
    });

    alertDialog.setPositiveButton("Save",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                    Code.audioName = editTextAudioName.getText().toString()
                            .trim();

                    recorder = new MediaRecorder();
                    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                    recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
                    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
                    recorder.setOutputFile(getFilename());
                    recorder.setOnErrorListener(errorListener);
                    recorder.setOnInfoListener(infoListener);

                    try {
                        recorder.prepare();
                        recorder.start();

                        if (Code.i == true) {
                            new Timer().schedule(new TimerTask() {
                                @Override
                                public void run() {
                                    runOnUiThread(new Runnable() {
                                        @Override
                                        public void run() {
                                            stopRecording();
                                            enableButtons(false);
                                        }
                                    });
                                }
                            }, 41000);
                        } else {
                            new Timer().schedule(new TimerTask() {
                                @Override
                                public void run() {
                                    runOnUiThread(new Runnable() {
                                        @Override
                                        public void run() {
                                            stopRecording();
                                            enableButtons(false);
                                        }
                                    });
                                }
                            }, 21000);
                        }
                    } catch (IllegalStateException e) {
                        e.printStackTrace();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    myChronometer.setBase(SystemClock.elapsedRealtime());
                    myChronometer.start();
                }
            });

    alertDialog.setNegativeButton("Cancel",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                    enableButtons(false);
                }
            });
    alertDialog.show();

Answer 1

setView方法： -

将自定义视图设置为Dialog的内容。如果提供 view是ListView的一个实例，将使用浅色背景。

所以你需要在某些布局中添加两个视图，例如LinearLayout，然后调用setView方法

Answer 2

这是因为您要将视图设置为警告对话框两次。首先定义一个Linearlayout，然后将视图（编辑文本和微调器）添加到其中，然后将Linearlayout设置为Alert Dialog。

LinearLayout parentLayout = new LinearLayout（                           RecordAudio.this）;

LinearLayout.LayoutParams linearParams = new   LinearLayout.LayoutParams（                           LayoutParams.WRAP_CONTENT，                           LayoutParams.WRAP_CONTENT）;

final EditText editTextAudioName = new EditText（RecordAudio.this）;
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT);
editTextAudioName.setLayoutParams(lp);
parentLayout.addView(editTextAudioName);

final Spinner spinnerListData = new Spinner(RecordAudio.this);
RelativeLayout.LayoutParams lpSpinner = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT);
spinnerListData.setLayoutParams(lpSpinner);
 parentLayout.addView(spinnerListData);

android中的自定义警报对话框会覆盖其他对象
