第一个页面布局:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="@+id/button122"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="第一种" />
<Button
android:id="@+id/button123"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="第二种"/>
<TextView
android:id="@+id/textviewaa"
android:layout_width="match_parent"
android:layout_height="200dp"
android:hint="内容"/>
</LinearLayout>
</android.support.constraint.ConstraintLayout>
第一个界面实现:
package com.example.xiaojie.paomadeng;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
/**
* Created by xiaojie on 2017/11/15.
*/
public class FActivity extends Activity {
private TextView textV;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fayout);
Button btn = (Button) findViewById(R.id.button122);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(FActivity.this, TActivity.class);
FActivity.this.startActivity(intent);
}
});
Button btn1 = (Button) findViewById(R.id.button123);
btn1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(FActivity.this, TActivity.class);
startActivityForResult(intent,1);
}
});
textV = (TextView)findViewById(R.id.textviewaa);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.i("tag", "onActivityResult: dddd");
Log.i("tag", "onActivityResult: requestCode:" + requestCode);
Log.i("tag", "onActivityResult: resultCode" + resultCode);
Log.i("tag", "onActivityResult: data" + data.getStringExtra("name"));
String content = data.getStringExtra("name");
textV.setText(content);
}
}
第二个页面布局:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/huichuan"

android:layout_height="wrap_content"
android:text="回传"/>
<TextView
android:layout_width="match_parent"
android:layout_height="300dp"
android:hint="回传内容"/>
</LinearLayout>

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.View;
import android.widget.Button;
/**

public class TActivity extends Activity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tlayout);
Button btn1 = (Button) findViewById(R.id.huichuan);
btn1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent data = new Intent();
data.putExtra("name", "Mr.H");
setResult(100, data);
finish();
