Question

嘿我正在尝试进行对话。但整个对话框没有显示，只有底部的3个图像按钮显示：这里有什么问题？当我点击对话框内的按钮时，即使我做了一个开关盒，也没有任何反应。

routeType = (ImageButton)findViewById(R.id.saveRoute_activityType);
        routeType.setOnClickListener(typeListener);

SaveRouteActivity.java

这是我的倾听者。

View.OnClickListener typeListener = new OnClickListener() {
                public void onClick(View v) {

                    switch(v.getId()){
                    case R.id.saveRoute_activityType:
                        Dialog typedialog = new Dialog(SaveRouteActivity.this);
                        typedialog.setContentView(R.layout.customtype_dialog);
                        typedialog.setTitle("Select type");
                        typedialog.setCancelable(true);
                        typedialog.show();
                        break;

                    case R.id.dialog_btn1:
                        txtType.setText("Run");
                        routeType.setBackgroundResource(R.drawable.track_run);
                        break;

                    case R.id.dialog_btn2:
                        txtType.setText("Bike");
                        routeType.setBackgroundResource(R.drawable.track_bike);
                        break;

                    case R.id.dialog_btn3:
                        txtType.setText("Walk");
                        routeType.setBackgroundResource(R.drawable.track_walk);
                        break;

                    case R.id.dialog_btn4:
                        txtType.setText("Ski");
                        routeType.setBackgroundResource(R.drawable.track_ski);
                        break;

                    case R.id.dialog_btn5:
                        txtType.setText("Boat");
                        routeType.setBackgroundResource(R.drawable.track_boat);
                        break;

                    case R.id.dialog_btn6:
                        txtType.setText("Snowboarding");
                        routeType.setBackgroundResource(R.drawable.track_snow_boarding);
                        break;
                    }

                }
            };

我的猜测是typedialog.setContentView(R.layout.customtype_dialog);被忽略，因为Dialog尚未膨胀。要解决此问题，您应该创建Dialog的子类，并在其setContentView()方法中调用onCreate()。

ImageButton +对话框问题
