As we all know, life is a long process of constantly overcoming difficulties and reflecting on progress. In this process, there will be a lot of questions and thoughts about life, so I decided to share my thoughts, experiences and stories to find resonance!!

Focus on Android/Unity and various game development tips, as well as various resource sharing (websites, tools, materials, source code, games, etc.)

😜 Chip to monitor

Selected listening: setOnCheckedChangeListener, the monitor only set the checkable property is true or use the filter/entry/choice 】 【 to come into force when the three style theme.

Click event listener: setOnClickListener

The close button was clicked listening: setOnCloseIconClickListener

Java

myChip.setOnCloseIconClickListener(View.OnClickListener { v: View? ->
    // Perform service processing
    Log.e("TAG"."OnCreate: Icon click event after the Chip text")
})

myChip.setOnClickListener(View.OnClickListener { v: View? ->
    // Perform service processing
    Log.e("TAG"."OnCreate: Chip whole normal click event") }) myChip.setOnCheckedChangeListener(CompoundButton.OnCheckedChangeListener { buttonView: CompoundButton? , isChecked: Boolean ->// Perform service processing
    Log.e("TAG"."OnCreate: Chip check status listener")})Copy the code

Kotlin

myChip.setOnCloseIconClickListener(v -> {
    // Perform service processing
    Log.e("TAG"."OnCreate: Icon click event after the Chip text");
});

myChip.setOnClickListener(v -> {
    // Perform service processing
    Log.e("TAG"."OnCreate: Chip whole normal click event");
});

myChip.setOnCheckedChangeListener((buttonView, isChecked) -> {
    // Perform service processing
    Log.e("TAG"."OnCreate: Chip check status listener");
});
Copy the code

😜 ChipGroup listening

myChipGroup.setOnCheckedChangeListener(new ChipGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(ChipGroup group, int checkedId) {
        // If the view id is in the layout, it is ok, but in fact, the sub-view should be added according to the interface data, how to distinguish these clicks?
        // We will do a complete example in the next article.
        Log.e("TAG"."OnCheckedChanged: Select the VIEW ID"); }});Copy the code
