我只想在activitymain中填充一些信息，然后将 Intent 传递给第二个 Activity ，首先它工作得很好，但是当我添加一些xml布局时，在设备上运行应用程序并传递 Intent 时它会崩溃
主要 Activity
public void move(View view) {
Intent i = new Intent(MainActivity.this, FormActivity.class);
EditText name = findViewById(R.id.name);
EditText animal = findViewById(R.id.animal);
String n = name.getText().toString();
String a = animal.getText().toString();
if (n.isEmpty() || a.isEmpty()) {
Toast.makeText(this, "nom ou animal est vide !", Toast.LENGTH_SHORT).show();
} else {
i.putExtra("KEY_Name", name.getText().toString());
i.putExtra("KEY_Animal", animal.getText().toString());
startActivity(i);
}
}
// and the formactivity or the second
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_form);
Intent i = getIntent();
TextView Text1 = findViewById(R.id.t1);
TextView Text2 = findViewById(R.id.t2);
String name = i.getStringExtra("KEY_Name");
String animal = i.getStringExtra("KEY_Animal");
Text1.setText(name);
Text2.setText(animal);
}
//Activity_main 的 XML 文件完美运行

最佳答案
第二个 XML 文件中引用的至少一个可绘制对象太大。
检查以下可绘制对象并调整它们的大小:
- 羊
- 标题
- list_fluid
PNG 通常不需要很大。如果可以的话，将它们保持在 1600x1600 以下，最好是 800x800。
关于java - 第二个 Activity 怎么崩溃了？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52725803/
