在一个活动中选中Android复选框，然后在另一个活动中显示按钮 [英] Android checkbox checked in one activity and then button appears in another activity

问题描述

问题说的一切。想象一下，有两个活动，活动A和活动B。当活动A的未选中按钮应该隐藏在活动B上时，选中的按钮应显示在活动B >

是主要活动

  public class MainActivity extends ActionBarActivity {
 
 private BubblesManager bubblesManager; 
 private boolean isCheckedValue; 
 
 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.activity_main）; 
 
 initializeBubblesManager（）; 
 
 
 final button add =（Button）findViewById（R.id.add）; 
 add.setOnClickListener（new View.OnClickListener（）{
 @Override 
 public void onClick（View v）{
 addNewBubble（）; 
 add.setEnabled ）; 
} 
}）; 
 
 CheckBox checkBox =（CheckBox）findViewById（R.id.add_fb）; 
 checkBox.setOnCheckedChangeListener（new CompoundButton.OnCheckedChangeListener（）{
 @Override 
 public void onCheckedChanged（CompoundButton buttonView，boolean isChecked）{
 
 isCheckedValue = isChecked; 
 
 Intent intent = new Intent（MainActivity.this，PopUpWindow.class）; 
 intent.putExtra（yourBoolName，isCheckedValue）; 
 
 
} 
}）; 
 
 
 
} 
 private void addNewBubble（）{
 BubbleLayout bubbleView =（BubbleLayout）LayoutInflater.from（MainActivity.this）.inflate layout.bubble_layout，null）; 
 bubbleView.setOnBubbleRemoveListener（new BubbleLayout.OnBubbleRemoveListener（）{
 @Override 
 public void onBubbleRemoved（BubbleLayout bubble）{
 finish（）; 
 System.exit ）; 
} 
}）; 
 bubbleView.setOnBubbleClickListener（new BubbleLayout.OnBubbleClickListener（）{
 
 @Override 
 public void onBubbleClick（BubbleLayout bubble）{
 Intent in = new Intent（MainActivity.this ，PopupWindow.class）; 
 startActivity（in）; 
} 
}）; 
 bubbleView.setShouldStickToWall（true）; 
 bubblesManager.addBubble（bubbleView，60，20）; 
} 
  

下面是下一个活动aka'activity B'

> public class PopUpWindow extends Activity {

@Override
protected void onCreate（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）;
setContentView（R.layout.activity_pop_up_window）;


DisplayMetrics dm = new DisplayMetrics（）;
getWindowManager（）。getDefaultDisplay（）。getMetrics（dm）;

int width = dm.widthPixels;
int height = dm.heightPixels;

getWindow（）。setLayout（（int）（width * .8），（int）（height * .6））;

Boolean yourBool = getIntent（）。getBooleanExtra（yourBoolName，false）;
Button fbbutton1 =（Button）findViewById（R.id.fbbutton1）;
if（yourBool）{
//显示按钮
fbbutton1.setVisibility（View.VISIBLE）;
}


}


点击复选框时要显示的按钮的XML代码

 < Button 
 android：visibility =gone 
 android：id =@ + id / fbbutton1
 android：onClick =button
 android：background =@ drawable / fbcircle
 android：layout_width =50dp 
 android：layout_height =50dp/> 
  

解决方案

  MainActivity扩展了ActionBarActivity {
 private BubblesManager bubblesManager; 
 private boolean isCheckedValue; 
 
 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.activity_main）; 
 
 initializeBubblesManager（）; 
 
 
 final button add =（Button）findViewById（R.id.add）; 
 add.setOnClickListener（new View.OnClickListener（）{
 @Override 
 public void onClick（View v）{
 addNewBubble（）; 
 add.setEnabled ）; 
} 
}）; 
 
 CheckBox checkBox =（CheckBox）findViewById（R.id.add_fb）; 
 checkBox.setOnCheckedChangeListener（new CompoundButton.OnCheckedChangeListener（）{
 @Override 
 public void onCheckedChanged（CompoundButton buttonView，boolean isChecked）{
 
 isCheckedValue = isChecked; 
 //取消注释这个代码，如果你想在检查更改时进入第二个活动
 // 
 // Intent intent = new Intent（MainActivity.this，PopUpWindow.class）; 
 // intent.putExtra（yourBoolName，isCheckedValue）; 
 // startActivity（intent）; 
} 
}）; 
 
} 
 private void addNewBubble（）{
 BubbleLayout bubbleView =（BubbleLayout）LayoutInflater.from（MainActivity.this）.inflate（R.layout.bubble_layout，null）; 
 bubbleView.setOnBubbleRemoveListener（new BubbleLayout.OnBubbleRemoveListener（）{
 @Override 
 public void onBubbleRemoved（BubbleLayout bubble）{
 finish（）; 
 System.exit ）; 
} 
}）; 
 bubbleView.setOnBubbleClickListener（new BubbleLayout.OnBubbleClickListener（）{
 
 @Override 
 public void onBubbleClick（BubbleLayout bubble）{
 Intent in = new Intent（MainActivity.this ，PopupWindow.class）; 
 in.putExtra（yourBoolName，isCheckedValue）; 
 startActivity（in）; 
} 
} 
 bubbleView.setShouldStickToWall（true）; 
 bubblesManager.addBubble（bubbleView，60，20）; 
} 
} 
 
 
 public class PopUpWindow extends Activity {
 
 
 @Override 
 protected void onCreate Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 
 setContentView（R.layout.activity_pop_up_window）; 
 
 
 DisplayMetrics dm = new DisplayMetrics（）; 
 getWindowManager（）。getDefaultDisplay（）。getMetrics（dm）; 
 
 int width = dm.widthPixels; 
 int height = dm.heightPixels; 
 
 getWindow（）。setLayout（（int）（width * .8），（int）（height * .6））; 
 
 Boolean yourBool = getIntent（）。getBooleanExtra（yourBoolName，false）; 
 Button fbbutton1 =（Button）findViewById（R.id.fbbutton1）; 
 if（yourBool）{
 //显示按钮
 fbbutton1.setVisibility（View.VISIBLE）; 
} 
 
 
} 
} 
  

The question says it all. Imagine there are 2 activity's, 'Activity A' and 'Activity B'.'Activity A' holds a checkbox when its checked a button should show on 'Activity B' when its unchecked the button should hide on 'Activity B'

below is the main activity

    public class MainActivity extends ActionBarActivity {

    private BubblesManager bubblesManager;
    private boolean isCheckedValue;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initializeBubblesManager();


        final Button add = (Button) findViewById(R.id.add);
        add.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                addNewBubble();
                add.setEnabled(false);
            }
        });

        CheckBox checkBox = (CheckBox)findViewById(R.id.add_fb);
        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                isCheckedValue = isChecked;

                Intent intent = new Intent(MainActivity.this, PopUpWindow.class);
                intent.putExtra("yourBoolName", isCheckedValue );


            }
        });



    }
 private void addNewBubble() {
        BubbleLayout bubbleView = (BubbleLayout)LayoutInflater.from(MainActivity.this).inflate(R.layout.bubble_layout, null);
        bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() {
            @Override
            public void onBubbleRemoved(BubbleLayout bubble) {
                finish();
                System.exit(0);
            }
        });
        bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() {

            @Override
            public void onBubbleClick(BubbleLayout bubble) {
                Intent in = new Intent(MainActivity.this, PopUpWindow.class);
                startActivity(in);
            }
        });
        bubbleView.setShouldStickToWall(true);
        bubblesManager.addBubble(bubbleView, 60, 20);
    }

Below is the next activity aka 'activity B'

public class PopUpWindow extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_pop_up_window);


    DisplayMetrics dm = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(dm);

    int width = dm.widthPixels;
    int height = dm.heightPixels;

    getWindow().setLayout((int)(width*.8),(int)(height*.6));

    Boolean yourBool = getIntent().getBooleanExtra("yourBoolName",false);
    Button fbbutton1 = (Button)findViewById(R.id.fbbutton1);
    if(yourBool){
            //For Displaying Button
        fbbutton1.setVisibility(View.VISIBLE);
    }


}

Below is the XML code for the button I want show when checkbox is clicked

<Button
        android:visibility="gone"
        android:id="@+id/fbbutton1"
        android:onClick="button"
        android:background="@drawable/fbcircle"
        android:layout_width="50dp"
        android:layout_height="50dp" />

解决方案

public class MainActivity extends ActionBarActivity {
private BubblesManager bubblesManager;
private boolean isCheckedValue;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    initializeBubblesManager();


    final Button add = (Button) findViewById(R.id.add);
    add.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) {
            addNewBubble();
            add.setEnabled(false);
        }
    });

    CheckBox checkBox = (CheckBox)findViewById(R.id.add_fb);
    checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            isCheckedValue = isChecked;
// un-comment this code if you want to go to second activity when check change 
//
//                Intent intent = new Intent(MainActivity.this, PopUpWindow.class);
//                intent.putExtra("yourBoolName", isCheckedValue );
//  startActivity(intent);
        }
    });

}
 private void addNewBubble() {
        BubbleLayout bubbleView = (BubbleLayout)LayoutInflater.from(MainActivity.this).inflate(R.layout.bubble_layout, null);
        bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() {
            @Override
            public void onBubbleRemoved(BubbleLayout bubble) {
                finish();
                System.exit(0);
            }
        });
        bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() {

            @Override
            public void onBubbleClick(BubbleLayout bubble) {
                Intent in = new Intent(MainActivity.this, PopUpWindow.class);
            in.putExtra("yourBoolName", isCheckedValue );
                startActivity(in);
            }
        });
        bubbleView.setShouldStickToWall(true);
        bubblesManager.addBubble(bubbleView, 60, 20);
    }
}


   public class PopUpWindow extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

setContentView(R.layout.activity_pop_up_window);


DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

int width = dm.widthPixels;
int height = dm.heightPixels;

getWindow().setLayout((int)(width*.8),(int)(height*.6));

Boolean yourBool = getIntent().getBooleanExtra("yourBoolName",false);
Button fbbutton1 = (Button)findViewById(R.id.fbbutton1);
if(yourBool){
        //For Displaying Button
    fbbutton1.setVisibility(View.VISIBLE);
    }


}
}
