没有意向在不同活动之间的切换工作正常 [英] Intent not working properly in switch between different activities

问题描述

我已用5 activities-calculator1.java，calculator2.java，deposit.java，calculator3.java，calculator4.java分别的应用程序，在活动1有一个切换按钮和下一个按钮，和所有其他的活动包含了下一个按钮，现在我想是时候切换按钮为pressed然后下一步按钮pressed它应该转到calculator2.java，并从calculator2.java，当我preSS下一个按钮，如果切换按钮calculator.java是上，它应该去别的deposit.java去calculator3.java，

I have made an application with 5 activities-calculator1.java,calculator2.java,deposit.java,calculator3.java,calculator4.java respectively,In activity 1 there is a toggle button and a next button,and all the other activities contains a next button,Now i want is when toggle button is pressed and next button pressed then it should goto calculator2.java,and from calculator2.java,when i press next button,if the "toggleButton" of calculator.java is "on" it should go to deposit.java else go to calculator3.java,

我的code是如下：（上单击下一步按钮）：

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();
            }
        });

推荐答案

由于 Calculator1.java 的

intent.putExtra("toggleBtn", tg.isChecked());

在 Calculator2.java

final boolean val= getIntent().getExtras().getBoolean("toggleBtn");

而不是最终布尔VAL = getIntent（）getExtras（）getBoolean（TG）;
