我创建了一个从RelativeLayout扩展的视图，其中包含一些ImageView，其中包含onClick个侦听器。
但是，它不起作用，我试图展示Toast但没有成功。
我误解了一些关于View的事情。
这是我的代码： （片段包含XML格式的视图）
public class Timeline extends RelativeLayout {
private Context context;
private ImageView imageViewFirstStep;
private ImageView imageViewSecondStep;
private ImageView imageViewThirdStep;
private ImageView imageViewEndStep;
private View timelineView;
private int viewWidth;
private RelativeLayout relativeLayout;
private Drawable drawableFirstStep;
private Drawable drawableSecondStep;
private Drawable drawableThirdStep;
private Drawable drawableEndStep;
private RelativeLayout.LayoutParams layoutParamsStep;
private ProcessActivity activity;
public Timeline(Context context) {
super(context);
activity = (ProcessActivity) context;
init();
}
public Timeline(Context context, AttributeSet attrs){
super(context, attrs);
activity = (ProcessActivity) context;
init();
}
public Timeline(Context context, AttributeSet attrs, int defStyle){
super(context, attrs, defStyle);
activity = (ProcessActivity) context;
init();
}
public void init() {
inflate(getContext(), R.layout.timeline, this);
this.context = getContext();
this.imageViewFirstStep = (ImageView) findViewById(R.id.timeline_first_step);
this.imageViewSecondStep = (ImageView) findViewById(R.id.timeline_second_step);
this.imageViewThirdStep = (ImageView) findViewById(R.id.timeline_third_step);
this.imageViewEndStep = (ImageView) findViewById(R.id.timeline_end_step);
this.timelineView = (View) findViewById(R.id.timeline_timeline);
this.relativeLayout = (RelativeLayout) findViewById(R.id.timeline);
}
public void setTimelineImages(int firstStep, int secondStep,
int thirdStep, int endStep){
viewWidth = timelineView.getWidth();
drawableFirstStep = context.getResources().getDrawable(firstStep);
drawableSecondStep = context.getResources().getDrawable(secondStep);
drawableThirdStep = context.getResources().getDrawable(thirdStep);
drawableEndStep = context.getResources().getDrawable(endStep);
imageViewFirstStep.setImageDrawable(drawableFirstStep);
imageViewSecondStep.setImageDrawable(drawableSecondStep);
imageViewThirdStep.setImageDrawable(drawableThirdStep);
imageViewEndStep.setImageDrawable(drawableEndStep);
imageViewSecondStep.setPadding(viewWidth / 3, 0, 0, 0);
imageViewThirdStep.setPadding((viewWidth / 3) * 2, 0, 0, 0);
imageViewEndStep.setPadding(viewWidth, 0, 0, 0);
imageViewFirstStep.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
AtelierFragment atelierFragment = new AtelierFragment();
activity.showTest(atelierFragment);
/*AtelierFragment atelierFragment = (AtelierFragment) activity.getFragmentManager().findFragmentById(R.id.container);
FragmentTransaction fragmentTransaction =
activity.getFragmentManager().beginTransaction().replace(R.id.container, atelierFragment);
fragmentTransaction.commit();*/
Toast.makeText(v.getContext(), "test", Toast.LENGTH_LONG).show();
}
});
imageViewSecondStep.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
imageViewThirdStep.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
imageViewEndStep.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
/*
* set le texte affiché dans les images de la timeline en fonction des string passés en paramètre
* */
public void setTimelineTextView(String Step, TextView textViewStep, int position){
textViewStep = new TextView(context);
textViewStep.setText(Step);
Typeface face = Typeface.createFromAsset(context.getAssets(),
"fonts/TradeGothic-BoldCondTwenty.otf");
textViewStep.setTypeface(face);
}
我的观点的XML：
