我想在单个TextView上显示3个EditText值

Question

如何在TextView tv上显示按钮b1上点击事件后3个编辑文本，et1，et2，et3的连接值？

我写了这段代码......

onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    b1=(Button)findViewById(R.id.b1);
    tv=(TextView)findViewById(R.id.tv4);

    et1=(EditText)findViewById(R.id.et1);
    et2=(EditText)findViewById(R.id.et2);
    et3=(EditText)findViewById(R.id.et3);

    b1.setOnClickListener(new View.OnClickListener(){

        public void onClick(View v){

            String name,age,contact;

             name=et1.getText().toString();
            tv.setText(name);

            age=et2.getText().toString();
            tv.setText(age);

            contact=et3.getText().toString();
            tv.setText(contact);
        }
    });

Answer 1

您可以尝试这样

b1.setOnClickListener(new View.OnClickListener(){

    public void onClick(View v){

        String name,age,contact;

         name=et1.getText().toString();
         age=et2.getText().toString();
         contact=et3.getText().toString();

        tv.setText(name + " "+ age + " "+contact);
    }
});

问题评论中Divyesh Patel的解决方案：

b1.setOnClickListener(new View.OnClickListener(){

            public void onClick(View v){

                String name,age,contact;

                 name=et1.getText().toString();
                age=et2.getText().toString();
                contact=et3.getText().toString();
                tv.setText(name+age+contact);
            }
        });
