[英]Calculate percentage of checked checkbox after press a button and show percentage in another activity (android)
[英]Android checkbox checked in one activity and then button appears in another activity
问题就是这一切。 想象一下,有2个活动,'活动A'和'活动B'。'活动A'保持一个复选框,当检查按钮应该显示在'活动B'时,如果未选中该按钮应该隐藏在'活动B'上
以下是主要活动
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(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);
}
下面是下一个活动,即'活动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);
}
}
下面是单击复选框时我想要显示的按钮的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" />
在活动B中使用intent bundle发送boolean值。如果是true,则显示按钮或隐藏它。
//global value
private boolean isCheckedValue;
CheckBox checkBox = (CheckBox)findViewById(R.id.chkbox1);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
isCheckedValue = isChecked; //first set value then assign to boolean extra.
Intent intent = new Intent(MainActivity.this, PopUpWindow.class);
intent.putExtra("yourBoolName", isCheckedValue );
startActivity(intent);
}
});
}
有意发送
Intent intent = new Intent(this, AcitivityB.class);
intent.putExtra("yourBoolName", isCheckedValue );
startActivity(intent)
在Acitivity B上处理
Boolean yourBool = getIntent().getExtras().getBoolean("yourBoolName");
if(yourBool){
//display button
}
else{
//hide button
}
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);
}
}
}
更改您的活动'A'像这样:
public class MainActivity extends ActionBarActivity {
private BubblesManager bubblesManager;
private boolean isCheckedValue;
private Intent intent;
@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);
}
});
intent = new Intent(MainActivity.this, PopUpWindow.class);
CheckBox checkBox = (CheckBox)findViewById(R.id.add_fb);
checkBox.setOnCheckedChangeListener (newCompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
isCheckedValue = isChecked;
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) {
startActivity(intent);
}
});
bubbleView.setShouldStickToWall(true);
bubblesManager.addBubble(bubbleView, 60, 20);
}
并在活动'B'中获得捆绑额外的价值
boolean checkedStatus= getIntent().getBooleanExtra("yourBoolName",false);
if(checkedStatus){
// Do your job here
}else{
}
在复选框的保存状态中使用布尔isChecked'活动A',在'活动B'上传递它,通过在'活动B'中使用该布尔集可见性到您的视图。
