我已经用5个活动做了一个应用程序--calculator1.java,calculator2.java,deposit.java,calculator3.java,calculator4.java,在活动1中有一个切换按钮和一个下一个按钮,以及所有其他活动包含一个下一个按钮,现在我想要的是当按下切换按钮并按下下一个按钮然后它应该转到calculator2.java,并且当我按下按钮时,如果calculator.java的“toggleButton”是“在“它应该去deposit.java否则转到calculator3.java,
我的代码如下:(点击下一个按钮):
Calculator1.java
btn2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(Calculator_1Activity.this, Calculator2.class);
intent.putExtra("toggleBtn", tg.isChecked());
startActivity(intent);
}
});
Calculator2.java
btn2.setOnClickListener(new OnClickListener() {
final boolean val= getIntent().getExtras().getBoolean("tg");
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(val==true){
Intent iq=new Intent(Calculator2.this,Deposit.class);
startActivity(iq);
}
else{
Intent ir= new Intent(Calculator2.this,Calculator_3Activity.class);
startActivity(ir);
}
}
});
Deposit.java
btn2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent iy = new Intent(Deposit.this,Calculator_3Activity.class);
startActivity(iy);
}
});
Calculator3.java
btn2.setOnClickListener(new OnClickListener() {
// final boolean val= getIntent().getExtras().getBoolean("tg");
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i1=new Intent(Calculator_3Activity.this ,Calculator_4Activity.class);
startActivity(i1);
//finish();
}
});
答案 0 :(得分:2)
Calculator1.java 有
intent.putExtra("toggleBtn", tg.isChecked());
Calculator2.java 中的
final boolean val= getIntent().getExtras().getBoolean("toggleBtn");
而不是final boolean val= getIntent().getExtras().getBoolean("tg");

<强> Calculator1.java 强>
btn2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(Calculator_1Activity.this, Calculator2.class);
intent.putExtra("toggleBtn", tg.isChecked());
startActivity(intent);
}
});
<强> Calculator3.java 强>
final boolean val= getIntent().getExtras().getBoolean(**"toggleBtn"**);
