Question

我有一些线性布局的TextViews，EditTexts和Buttons。如果我触摸/单击LinearLayout的任何一侧，它将转到下一个活动。我已经尝试为LinearLayout中的所有元素设置onClick侦听器。这有效但有没有办法编写代码来触摸LinearLayout的任何区域以进行下一个活动而无需为所有元素添加onClick处理程序？因为布局中有更多元素。请帮助我。

Answer 1

尝试从代码中为linerlayout设置onClick listener事件，如下所示

LinearLayout l1 = (LinearLayout)findViewById(R.id.layout1);
l1.setOnClickListener(this);
l1.setClickable(true);

Answer 2

试试这个。

login.java

package com.android;


import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class Login extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button newuser = (Button) findViewById(R.id.Button02);
        newuser.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                Intent myIntent = new Intent(view.getContext(), Register.class);
                startActivityForResult(myIntent, 0);
            }

        });
    }
}




Register.java


package com.android;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class Register extends Activity {

    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.register);

        Button register = (Button) findViewById(R.id.Button03);
        register.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                Intent intent = new Intent();
                setResult(RESULT_OK, intent);
                finish();
            }

        });
    }}
