用於手風琴菜單的Android背景顏色

我希望Java文件中的代碼能夠設置任何按鈕被點擊的背景顏色，並保留它，即使您放開按鈕後也是如此。在此先感謝用於手風琴菜單的Android背景顏色

我真的沒有在這裏格式化。我希望很清楚什麼屬於哪裏。

的Java：

package mika.actual; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 

public class accordion extends Activity { 
    /** Called when the activity is first created. */ 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.accordian); 

     Button btnProfile = (Button) findViewById(R.id.btnProfile); 
     Button btnSettings = (Button) findViewById(R.id.btnSettings); 
     Button btnPrivacy = (Button) findViewById(R.id.btnPrivacy); 

     View panelProfile = findViewById(R.id.panelProfile); 
     panelProfile.setVisibility(View.GONE); 

     View panelSettings = findViewById(R.id.panelSettings); 
     panelSettings.setVisibility(View.GONE); 

     View panelPrivacy = findViewById(R.id.panelPrivacy); 
     panelPrivacy.setVisibility(View.GONE); 

     btnProfile.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // DO STUFF 
       View panelProfile = findViewById(R.id.panelProfile); 
       panelProfile.setVisibility(View.VISIBLE); 

       View panelSettings = findViewById(R.id.panelSettings); 
       panelSettings.setVisibility(View.GONE); 

       View panelPrivacy = findViewById(R.id.panelPrivacy); 
       panelPrivacy.setVisibility(View.GONE); 

      } 
     }); 

     btnSettings.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // DO STUFF 
       View panelProfile = findViewById(R.id.panelProfile); 
       panelProfile.setVisibility(View.GONE); 

       View panelSettings = findViewById(R.id.panelSettings); 
       panelSettings.setVisibility(View.VISIBLE); 

       View panelPrivacy = findViewById(R.id.panelPrivacy); 
       panelPrivacy.setVisibility(View.GONE); 

      } 
     }); 

     btnPrivacy.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // DO STUFF 
       View panelProfile = findViewById(R.id.panelProfile); 
       panelProfile.setVisibility(View.GONE); 

       View panelSettings = findViewById(R.id.panelSettings); 
       panelSettings.setVisibility(View.GONE); 

       View panelPrivacy = findViewById(R.id.panelPrivacy); 
       panelPrivacy.setVisibility(View.VISIBLE); 

      } 
     }); 

    } 

}

您是否考慮過使用選擇器？ – joao2fast4u

你基本上想要一個選定/未選中狀態，是嗎？ – joao2fast4u

如果我理解正確的話，你想要做的是，點擊一個按鈕，並擴大其子菜單時，更改背景是什麼直到再次點擊該按鈕。你可以用按鈕上的標籤做到這一點：

btnSettings.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     // DO STUFF 
     //if button is not selected, change background and tag the View as selected 
     if(v.getTag() == null || v.getTag().equals("not_selected")) { 
      v.setBackgroundColor(Color.RED); 
      v.setTag("selected"); 
      //show sub-menu 
     } 
     //if button is already selected, reset background and tag the View as not selected 
     else{ 
      v.setBackgroundResource(android.R.drawable.btn_default); 
      v.setTag("not_selected"); 
      //hide sub menu 
     } 

    } 
});

注意v.setBackgroundResource(android.R.drawable.btn_default);正在重置按鈕背景到Android繪製。您可能想要將其更改爲自定義繪圖或顏色。你可以使用ExpandableListView來實現這種菜單。

謝謝。我對此很新，所以感謝提示。我會研究它。 – lenny

button.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       if (event.getAction() == MotionEvent.ACTION_DOWN) { 
        view.setBackgroundColor(ContextCompat.getColor(context, R.color.presed_color)); 
       } else if (event.getAction() == MotionEvent.ACTION_UP) { 
        view.setBackgroundColor(ContextCompat.getColor(context, R.color.unpresed_color)); 
       } 
       return false; 
      } 
     });
